Recently bought an incredible 'supercomputer' from this company. I was referred by an office colleague who also went to DCA Computers to get huge horsepower for faster rendering capability. I went with my other quotes which they looked at. They asked questions and spec'd up an overclocked i7 tower. It achieves an incredible rendering benchmarking score. Like, faster than anything I have seen reviewed on the Net. I am so enthralled I keep throwing my old and hardest jobs at it which it grinds through in seconds. It is completely stable, I'm soooo chuffed. I wound up paying 20% less than my cheapest quote for a similar spec, and this thing is much faster. I can’t recommend this company enough. They even called 3 days later and asked if I was happy with the performance. So there is my review. --Chris Purchased a DCA i5 machine which I am very happy with. Quality PC and cheap as chips. Arrived earlier than expected. --Robert Coulston Bought my second overclocked computer from DCA this week and it rocks! I sent them a spec I had researched, they recommended something different, the bottom line cost was lower, and now it kicks arse. What more could I have asked for. I opened it up and its a work of art in there. By the way I used to be a computer technician. --Glenn S. After being given the run around from our superstore computer giants, I was referred to DCA Computers @ Castle Hill from a colleague and I was IMPRESSED! The team is awesome, but one member particularly stands out – Erik Madden. Rather than selling me the biggest, most expensive supercomputer on the market – he took the time to sit down with me and go through a needs analysis which cleared up a lot of conflicting advice by others. Best part was no pressure or hard selling tactics to meet his end of month targets, unlike our other friends. He was extremely helpful, professional and has a high technical aptitude but speaks plain English too! After I bought from them, I still find that I can easily get after sales service or come in for that “technobable” chit-chat we always like to do! Highly recommended! --Richard Reliable computer company. I own a software development company. We use many high end computers and around half of them have come from DCA. The DCA computers are all high end and very reliable. We pay around half the price for these configurations relative to other high end quality PCs. Also DCA is very receptive and technically competent with phone support. I can recommend this company. --Graham Brogan. DCA - Our only computer provider for over 5 years. I have been using DCA Computers for over 5 years for all my personal and business computer requirements. DCA has helped us update our existing computers over the years to keep them humming along and when it became necessary for a complete replacement they supplied us with custom made new boxes that have been working 24 hours a day with no problems from day one. Their advice and prompt service has always been given in a pleasant and friendly way with nothing being too much of a problem. I can highly recommend DCA Computers to anyone looking for great advice with any computer issue either repairs or purchase of new or second hand equipment, my mother of 85 is using a great second hand PC purchased from DCA and has never had a problem with it for the 3 years she has been using it. So if you every need repairs, new or 2nd hand computers or just some advice, I suggest you call DCA first! --Greg DCA FTW DCA has been my solution to all things tech related for a few years now, I've always found their service and knowledge levels to meet or exceed expectations. Being an avid gamer I've had several high end gaming machines designed, built and tested by DCA and have been more than happy with the performance, reliability and cost of each reincarnation of the "gaming beast". I've found DCA to be very good at delivering bang for your buck, selling you the components you need to deliver the frame rate you want, while not overselling you with things you don't really need, also providing very competitive and stable overclocking. I've no hesitation in recommending DCA, good people, great service and competitive pricing. --Marty Really good service! Been going to DCA for awhile now buying bits a pieces, really good prices and friendly staff. Best thing is they can always solve problems that I've been struggling with for days and recommend me the best products and not sell me something I don't need. --David Highly recommended I've used DCA for several years. I mostly buy parts and equipment for system integration and other work, but I've also had numerous systems supplied built and tested by the always helpful staff. If they don't have an answer straight away, you don't get any superfluous sales speak, they simply tell you that they'll find out and get back to you, and they always do. When systems "just work" as they almost always do, it's pretty easy to keep people happy. For me though, the real indication of how professional the staff at DCA are is how they handle faults, failures or other less than typical situations. I can honestly say I've never had a transaction with DCA I've been less than very pleased with. I've absolutely no hesitation in recommending services. --John T. A Family of happy customers. My family and I have been customers of DCA Computers for many years now, so to Dave, Glenn and the team at DCA Computers; a very big thankyou for all of the help and support you have given to the family thus far and we look forward many more years of the same. All eight of our home and two business computers, along with printers, all of the software, upgrades and repairs have been sourced, purchased or provided through Dave and his team. I have recommended DCA Computers to my friends who have also purchased and upgraded from DCA and their comments back to me have been as positive as mine are here. Its all too rare to get customer service these days but to get really good and courteous customer care and service is a bonus worth staying with, thats why we have never looked to anyone else for our PC needs and why we keep coming back. --Paul Long Term Client. I am a local onsite computer technician and have used DCA Computers for over 6 years now. I obtain parts and sometimes use them to provide a backup Onsite Service for when I am unable to get to my customer's. They have excellent tech's in house and onsite and have always helped me for most parts I require. --Michael S. Long Term Customer. A big Thank You for recent help. I have purchased several computers and many peripherals from DCA Computers over the last 9 years. I enjoy technology and teach computing to seniors. My PC's have had high end and unusual requirements to also accommodate my hobbies. My first PC purchased from DCA Computers 9 years ago has been donated to a friend and is still serving faithfully. I have been exceedingly pleased with subsequent PC's purchased from DCA. From time to time during these years I have when required, sought and received the most helpful and professional advice from any member of the DCA staff who answers the telephone . Why would I shop at DCA? Because all staff are extremely professional, helpful, really believe in AFTER SALES SERVICE and importantly, to their customers engender trust. So I will continue to shop at DCA in spite of several computer businesses conveniently located close by. I would strongly recommend DCA to any computer buyer or a person simply wanting to explore or seek information technology. --Terry From Steve @ Cherrybrook - A satisfied long time client As a professional IT consultant/technician I require a reliable IT goods supplier and except for some specialist items I have not had a need to look further than DCA Computers. I have sent quite a few of my clients directly to DCA over the years with either a shopping list or a to do list as I trust DCA to get it right and my worst case scenario if you could call it that was a phone call to confirm some details. In office/home PC support, setup/installation and tuition is my game and simply put DCA is my backup, I have no hesitations recommending them. Thank you very much DCA --Steve. Thankyou DCA I have been a client of DCA for over 5 years and have had 3 computers built by them. I really like the way they will customise the computer build to your needs, and the prices are very competitive. I have always found the staff very knowledgeable, friendly and helpful, and are willing to give advice over the phone. --Megan Professional system purchase. I am a professional programmer, and recently bought a custom iCore 7 / Windows 64 bit system from them. The customisation was easily handled by DCA, and the service and delivery was exactly as I expected. This deal was FAR better value than I could find from Dell, and other main stream suppliers! The sytem has been running smoothly, and I have no hesitation recommending DCA when you buy your next setup. Already others I have talked to agree with the quality / pricing standard. --Jim. Outstanding service!! Thanks so much for helping me identify and remove that mytob virus. I previously spoke to a few other other IT support people who couldnt work out what the problem was and didnt have the time. You guys are so generous with your time, and your problem-solving skills are invaluable! I know where to go again next time I have a daunting problem like this! Eddie a Happy Customer. Over the years I have bought monitors, computers, etc from DCA and I have never had any problems. I have buy from them even though I live a distance away. Prices very competitive. But the best is the extremely friendly service. If I need advice or something explained all it takes is a phone call. All the staff are extremely knowledgeable and always have a ready answer. I guess I am biased, and why not with all the service I get. --Ed. Great service and advice with friendly and experienced staff. TML Media specialise in Wedding & Event Videography and I had my PC built specifically for video editing work and found the staff at DCA Computers to be very helpful. They gave me the right advice and discussed specific PC needs for my business. They were extremely helpful and most of all listened to my business needs to build me a PC that was exactly what I required. The price was also very reasonable and I would certainly go back to DCA Computers for any further computer needs for my business. --Monica. TML Wedding & Event Videography. Great Store !!! After buying my first PC from Harvey Norman (HP) and experiencing enormous difficulty and expense in upgrading components and servicing, I found my way to DCA Computers.I have bought all of my PC needs from these guys ever since ( nearly ten years). The service is so good that I actually consider these guys as friends. You cannot go wrong to shop here !!!! In fact you are mad if you don't !!!! --Dave Highly recommended for repairs & new systems. Cost effective & fast computer repairs. Our company has also purchased a server from here and 6 desktop machines over the past 5 years. No problems in this time, & excellent build quality. Knowledgeable staff. --M. The place to get your PC !! This place is the business...No bullshit, only sell quality stuff and at the cheapest prices...had a small hardware glitch (not their fault) and they replaced it immediately with no question. Friendly service...great prices. I am now a loyal customer. --M. Highly recommended for repairs & new systems. Cost effective & fast computer repairs. Our company has also purchased a server from here and 6 desktop machines over the past 5 years. No problems in this time, & excellent build quality. Knowledgeable staff. --David Helpful Australian speaking staff explain things so that you can understand it. They treat you like a human not a duffer suffering from "over stuffed wallet syndrome". A welcome change after dealing with a few stores before finally finding this one. Previously disappointed by other IT companies and ripped off blind. You will not have to take these guys to consumer affairs to get warranty! Prices are cheap, same or better than Harvey Norman, Power House, or Good Guys and definitely better than other PC places. They build awesome gaming machines, corporate systems and networks. No software other than Windows OEM , Office, and Anti-Virus. --Greg |
DCA Computers Recommended Testing and Benchmarking Utilities
Heres our pick of the best testing and benchmarking utilities out there. These are the tired and true choice of the DCA technical team.
Prime 95
Prime 95 itself is a program designed to try and discover new Prime numbers as part of GIMPS, the Great Internet Mersenne Prime Search. Prime 95 uses all spare CPU cycles on all CPU cores and is a great way to run a CPU at maximum capacity. It has a built in stress testing function which has been widely used for CPU stability testing and endorsed by overclockers for over 10 years. Available in either 32 bit or 64 bit formats.

CPU-Z
CPU-Z has been a standard part of every technician’s software collection for as long as I care to remember. CPU-Z provides an in depth analysis of your CPU including Name, Specifications, Stepping, Cache, Voltage and real time readout of current CPU frequency. Very handy to advise you exactly what speed your CPU is running at if you are overclocking. Also has information tabs for your Motherboard, Memory, Memory SPD Timings and more. Regularly revised and updated for new CPU models and is available in 32 and 64 bit versions.

ATTO Disk Benchmark
ATTO Disk benchmark is widely used in the computer industry to provide accurate performance analysis of hard disk drives, Solid State drives and RAID arrays by measuring read and write speeds of blocks of data ranging from 0.5KB to 8192KB. This can give a good indication as to whether the HDD is performing in line with the manufacturer’s specifications and can also give comparisons between different HDD controller chips with the same HDD attached.

GPU-Z
GPU-Z by Techpowerup is a utility which can probe your graphics card and display a wide range of information including GPU and memory frequency, temperature, fan speeds as well as detailed statistics of your specific GPU core such as pixel fill rate, memory bandwidth and number of shader units.

oZone3D Furmark
Furmark is a Graphics Card benchmarking and stability testing program which we regularly use here at DCA Computers, particularly if we suspect hardware faults in a graphics card which may be causing artefacting or other graphics anomalies. Furmark pushes a graphics card very hard and generates maximum heat output, which Furmark also logs with a handy graph.

Super Pi
Super Pi is a simple program which calculates Pi to a predefined number of decimal places. This program runs entirely in CPU cache and is a direct test of the calculating power of your CPU. The less time it takes for your CPU to calculate the result, the “faster” of more powerful your CPU is, and is a good test of relative CPU horsepower. Get all your friends to run Super Pi on their PCs to see who has the most powerful CPU!

3D Mark
3D Mark by Futuremark Corporation is pretty much a legend in the computer industry. For over 10 years, various versions of the 3Dmark program have been used to test the 3D graphics capabilities of gaming PCs. The most recent versions of 3D Mark are 3D Mark 2006 which can be used under Windows XP with a Direct X 9 compatible Graphics Card, 3D Mark Vantage, designed for Windows 7 or Windows Vista with a DirectX 10 compatible Graphics Card, and the latest incarnation 3D Mark11, designed for Windows 7 or Windows Vista and a DirectX 11 compatible Graphics Card.
