Memory, Hard Drive, Power Supply, Coolers

Part 2: Building A Balanced Gaming PC
By

The following components are outside the scope of comparison here, but still very important to the results we're generating. We don’t want to limit our system with too little memory, a slow hard drive, a flaky power supply, or high temperatures. So, we’ve gathered an assortment of complementary hardware to help address our needs throughout this series.

Special thanks to Corsair, Western Digital, and Xigmatek for arranging the hardware needed to make this entire series possible.

Memory

Corsair Dominator TR3X6G1600C8D

This 6GB triple-channel kit of Corsair Dominator memory is rated DDR3-1600 and CL 8-8-8-24 timings at 1.65V.  Corsair backs these modules with a lifetime warranty and uses DHX (Dual-path Heat Xchange) technology to keep them cool.

We’ll be utilizing either two or three sticks of this high-performance memory in each DDR3 platform tested, depending on whether the setup in question employs a dual- or triple-channel controller.

Corsair Dominator TWIN2X4096-8500C5DF G

For our DDR2 platforms, we’ll use a 4GB dual-channel kit of Corsair Dominator memory, rated DDR2-1066 and CL 5-5-5-15 2T timings at 2.1V. This kit is also cooled by DHX technology and backed by Corsair’s lifetime warranty.

Hard Drive

Western Digital Caviar Black WD6401AALS

The Western Digital Caviar Black 640GB hard drive offers gamers a good blend of capacity, performance, and affordability.

This 7,200 RPM, SATA 3 Gb/s drive has dual processors, 32MB cache, and is backed by a five year warranty. Bear in mind that using an SSD instead of a mechanical drive like this one will almost certainly improve level load times, but it's less likely to affect your actual in-game performance.

Power Supply

Corsair CMPSU-850HX 850W

The right combination of motherboard, processor, memory, and graphics cards means little without a quality power supply unit capable of providing reliable, clean voltage to our components.

Considering the overclocking desires and multi-GPU configurations that you'll see later in the series, we chose an 850W unit from Corsair. The modular Corsair CMPSU-850HX has a single 70A, +12V rail, six 6+2 pin PCIe power connectors, a seven year warranty, 80 PLUS Gold efficiency certification, and a 140mm temperature-controlled fan.

Coolers

Xigmatek HDT-S1283 & Dark Knight-S1283V

We're utilizing Xigmatek’s HDT-S1283 to cool our Socket AM3 and 775 processors, and the LGA 1366-compatible Dark Knight-S1283V to keep the Core i7-920 running cool. On both heatsinks, Xigmatek uses its HDT (Heatpipe Direct Touch) system for thermal transfer and a PWM-controlled 120mm fan, with rubber mounts for quiet operation.

    Please, if you want to criticise something make sure you've understood it (read in this case) thoroughly. Otherwise you'll look like an idiot.

    Anyway, this series is made out of win!
    Thank you.

    What effect does having a motherboard that unlocks the 4th core on the X2 and X3 have? In power consumption and overall performance? I'm not asking a redo of all the data, just asking for speculation by someone more knowledgeable, if I can get it.

    This article truly is revolutionary. I have been waiting for an article like this since I began building my own PCs ten years ago. This article coupled with your CPU and GPU hierarchy chart will go a long way towards eliminating CPU/GPU bottlenecks. This article truly is the first of its kind and I hope to see it at least twice a year if not four times a year. Thank you.

    Great article, it's educational, looking forward to ATI’s 5000’ series comparisons.

    In your conclusion, you state that a $100 CPU does a far better job than a $100 GPU when it comes to maxing out a low resolution like 1280x1024. Can you elaborate?

    Hooray! Now this is a good reference on the forums when people ask for bottlenecks

    How can this take weeks to plan? Perhaps if one works 15mins a day.

    Good to see vanilla HD4890 puts up a serious fight for GTX 285. Not that it gets any credit for that.

    You should stop using Vista. It's dead already.

    Good article. Will read parts 3&4.

    So now comes the next point - why are nvidia's GPU-s consistently requiring a faster CPU to show what they can do, while Radeons perform very well even with a dual core?
    Best example of course is the GTX295 - are nvidia-s drivers really that lousy, or is there something else at play?

    Good article. I was awaiting the part 2 showcasing AMD's line-up. I was starting to think you guys at Tom's forgot about it ;) 

    Overall a good article. But,I think these charts can be deceiving though to someone who is not well versed in PC gaming and the hardware involved.

    For example,I have a HD4850 paired with an aging system that incorporates an Athlon64x2 5200+ 2.6GHz Windsor(2x1MB L2 model), 2GB of DDR2 800 (5-5-5-15 timings) and using XP Home with the latest service pack.

    I have yet come across a game I cant play at acceptable frame rates. Granted, I'm not using an ultra-high resolution, but I do up the graphic settings to high/max. I play modern games, some of which are on these charts, and they all play just fine.

    By setting an arbitrary number of frame rates.. some at 40, and some at 45, as "acceptable" can be somewhat misleading. I think that if your gaming using the two of the lower resolutions represented in this article, then I think you'll be happy with one of the lower tiered CPUs and GPUs paired together. Those combination's will get you very played frame rates at the lower resolutions.

    If your going for the higher resolutions, then of course you would have to up the power of the system.. but, I contend that at the lower resolutions, the cheaper hardware will do just fine, and any more money spent is for benchmark numbers alone.

    Clearly the Phenom IIX3 720 is the Core 2 Duo annihilator because the advantage of its extra core...

    I'm returning my cards just bought on black friday pny gtx 260 core 216 and pny gtx 275 and exchange them for radeons 4890 and 5850. I'm definitely not going to pay for a new ring around i7-920 to get real benefits.

    Interesting article, I'm still shock about nvidia video card limitations, I can't understand why green cards are so CPU dependable. Are those expensive GPU not suppose to offload graphic tasks from CPU's? Why we have to spend more on GPU than a CPU?. I'm building a new ring only to play crysis and farcry2 and will not be spending more than $300 for CPU/motherboard/memory. Now 4890 It's on my list as first choice($179 on sale now), will avoid gtx285 even if they sell it for $200.

    look at the 5700 series really close really impressive cards starting to get some in stock paired with the 720 you really cant beat the price/performance combo. and the 5750 will nearly match a 4890 overclocked. under 300 with either card.

    I'm in agreement with KT_Wasp here. I've got a friend running a Core 2 Quad, one of the lower versions, not sure which but I think it's around 2.3 Ghz, and they've got a 4850, and they run all their games with the exception of Crysis at all high with no problems. I'm not sure what resolution they play at, but they've got a 1920x1080 screen, so it's definitely not 1024x768. But anyway, completely playable on games like Shattered Horizon and Dragon Age. I don't know what the actual framerates are, but it doesn't stutter at all with no dips and plays very smoothly.

    I wish you did the 4870, cause the 4890 is expensive (Well, more than I want to pay). And I already knew the 4850 wasn't good enough for what I want to run/do.
