Graphics: PowerColor Liquid-Cooled Radeon HD 5970

Looking for a better price on the performance seen in our previous-build’s twin Radeon HD 5870 graphics cards, we quickly decided on a single Radeon HD 5970. Beyond cost savings, the dual-GPU card allows easy upgrades to quad-GPU CrossFireX whenever graphics performance begins to feel “dated.” Fortunately, none of the air-cooled cards we would have chosen were available when we placed our order.

What turned the lack of air-cooled cards into a good thing was that it forced us to think beyond basic performance-per-dollar and instead consider the ultimate benefit of liquid cooling an ultra-hot card. Less hot air in the case means less extensive cooling requirements for other components like RAM and the CPU voltage regulator. Even the graphics card itself should overclock better with the limits of its stock cooling solution removed. Looking forward to future upgrades, a second air-cooled card could have partially blocked the cooling fan of the first, but liquid cooling avoids such conflicts.

RAM: Crucial DDR3-1333 CAS 9

Fortified with Micron’s D9KPT memory, Crucial’s unadorned DDR3-1333 CAS 9 modules consistently win our value-overclocking comparisons by reaching higher speeds at a lower price than competing brands that often use the same parts. Those second-place competitors have heat spreaders attached with double-sided thermal tape, a method we believe hinders cooling at the low-voltage levels used with Core i7 processors.

Supporting data rates as high as DDR3-1990 and DDR3-1600 latencies of 8-7-7-18, these low-key, low-cost CT3KIT25664BA1339 triple-channel 6GB kits have found their way into previous SBMs for nearly a year.

    zoemayneMore than 64GB is gonna be needed for multiple games and good apps... those ssd's can only handle 5 games max.


    You're repeatedly ignoring that it's 128GB, not 64GB, because the article repeatedly states that the drives are striped (Level 0) by the RAID controller. And there's a terabyte of added storage on top of that for stuff that isn't programs.

    I couldn't have made it better. Amazing rig for a 3k budget.

    Well, the explanation is in the conclusion, the builder wanted redundant storage instead of the big radiator but chose neither, leaving enough room in the budget for anyone who wanted to copy the build to make their own upgrade choice.

    But what's not in the budget is that the water was never hot, it was barely warm. The problem with running the CPU at 100% load and the GPU at 100% load is that the water temperature went up by around 10 degrees...we're talking about going from the 30's to the 40's here at full load. The article points to the GPU cooler as a likely flow restriction so I have three solutions:

    Solution 1: Add 1/2" by 3/8" adapter T's and cool the chipset block, parallel to the GPU block. That would allow some of the water to bypass the GPU cooler, which is OK since the GPU was always cold. But 1/2" by 3/8" T's are hard to find outside of a hardware store, and Newegg certainly doesn't have them.

    Solution 2: Switch to a 3-fan radiator. A 4-fan unit won't fit nicely into that case, and making an ugly system wasn't considered a solution.

    Solution 3: Add a second liquid-cooled 5970 parallel to the first. Get twice the GPU power and completely unblock the lines in the process. The GPUs would run slightly hotter when each gets only half the water, but at least the CPU block's flow won't be restricted. And...since it's probably adding another 10 degrees to the coolant...stick the three-fan radiator in there as well. For FOUR grand you could have a KILLER system!

    OK, so solution 1 is the cheapest, but you have to admit solution 3 is tempting...

    Nice fail there Zoe.

    This thing is a beast.

    Nice as it is, my only complaint is that...
    Overclocked 5970 + i7 on a single 120.2?
    ARE YOU MAD!
    Likely.

    Well, I personally would have dropped something else and gone for a 120.3 or 140.3 radiator. =D
    Hell, maybe even a 140.4 radiator, but then again, I like my system to run chilly and silent. It's also be very difficult to mount a 140.4 I assume. Maybe I could jack a radiator form work, I think it's about 1 metre by 3 metres by half a metre. Granted, it's for industrial use, but just for one day, please boss please?

    Good results on the i7 though. Decently low voltage and still managed to reach 4.3GHz. My i7 is a lemon. It makes me sad. =(
    Also an impressive overclock for a 5970.

    At this kind of power, you should be testing multi monitor resolutions. I have a 5770 and I run 7 megapixels, you use a 5970 and only run 4 megapixels.

    Looking forward tho the $1,500 build. See how my build compares to one six months older on a similar budget (and cry).

    I kinda like it. Dramatic power increase for the overclocked components. But also dramatic performance increase.

    Another solution to the constricted water flow would be to change the block on the 5970.

    This build gets one and a half thumbs up from me, not that anyone cares...

    Only changes I would've recommended is...

    Storage HDD: Samsung Spinpoint F3 1TB - $90
    RAM: G.SKILL PI Series 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 1600 - $180

    Those would still get you in at $3,000 provide an increase in performance with the Cas7 DDR3 1600 RAM and a faster hard drive (well, if you really need faster with two SSD in RAID0 :D  ).

    I don't know why someone marked down tecmo34 comments, if you going to mark down a comment at least have the good curtsey and explain why you disagree (unless it's blindingly obvious like the post left by tacoslave).

    I too would have used the Samsung Spinpoint F3 1Tb it's been reviewed countless times and benchmarked against all the competition and wins every time.

    So....You guys planning on giving this beauty away?

    Seriously though, great review. It makes me seriously consider switching to water.

    Will the prices continue to rise, will they level off, or will they decrease this Summer?

    Here is what I would like to see...

    Swap the case for a goliath sized Antec 1200, add another 5970 and a seperate water cooler 120.3 for the pair. Now the CPU and GPU's have a water supply independant from each other. Overclock that monster!

    The only thing I would have changed would be the case to a COOLER MASTER CM690 II Advanced. It already includes a mount for 2 SSD drives and can accommodate 2 radiators internally. Aside from that, very nice build and I look forward to a chance to win it... ;)

    There is a $3000 budget limit you know. Curious as to why you guys didn't go with the Vertex LE for the SSD. Granted it's only 100gb and was $400, but it's a very large boost in performance, putting even the Intel X25 G2 drives to shame.

    Those SandForce powered drives have amazing performence.. But that drive alone is nothing compared to the 64bg drives in raid0.. Plus you get an extra 28gb with the 2x64gb setup..
