So this is a $5,000 high end gaming PC that fully supports 4 way crossfire. I would primary use it for stream acceleration and extreme gaming considering shader count and ATI scalability. I know Barts XT series will come out but I don't know if the PSU fully supports 4 way. I'll have to wait and see. Give me ur thoughts...

Do you realize the human eye can not tell the difference between 60FPS and 300+FPS on a 60hz monitor?

Monitors nowadays are configurable to 75hz

Ok let me restate my self *clears throat*

Do you realize the human eye can not tell the difference between 75FPS and 300+FPS on a 75hz monitor?
October 9, 2010 9:37:48 PM

I thought the threshold for the human eye was 24-36fps?

(but then I keep getting told that us "gamers" and "computer geeks" aren't normal...)

Technically yes, 24 frames is the minimum number needed for appropriate visual smearing so that you dont see the gaps better them, however it needs to be a very stable 24 FPS. For gaming and other things that dont always have motion blur built into the image you need more frames to make it seem smooth, higher FPS helps makes things look smoother but wanting to your GPU trying to pump out 4 times as many frames per second as your monitor can handle is just a stupid waste of money.

If he has $5k to spend on a computer then let him, whether it's overkill or not. If I had that much money I'd do the same.
October 9, 2010 10:35:25 PM

5k on a rig is fine and all but some of it is just a SHEER waste , like why go 6x2gb????get bigger sticks....ram works best in its native channels 2 or 3. so if you want a lot of ram get 4gbx2 on dual channel or 4gbx3 on triple channel if you wanna get a shitload.

also Powercolor is a meh brand...but for your budget why not just Xfire 5970s instead? for the sheer sake of saying I HAVE 4 cards......just seems overkill and ohh u may want some better cooling with 4 cards....

2 Gb ram sticks are much more cheaper than 4 Gb modules. The previous benchmark link shows on average the 4x 5870 is about 60 FPS faster than 2x 5970. More ram works better with GPU hardware acceleration (Stream processing) like stated earlier.

Seems like you are here to argue, not for advice.

Well it doesn't seem like you're very worried about price with a $5k build...

If you're going this high end forget ati. 4 470s destroy anything ati brings to the table. Let's not even talk about 480s.
October 11, 2010 6:18:42 PM

With $5000, don't bother with 4x 5870's, get 3x GTX 480's. SLI scaling is much better than Crossfires. Also, a fourth GTX 480 wouldn't be worth it, from what I've seen, although the benchmarks were done some months ago.

First of all, the 4X 480 SLI setup will not hit 390 FPS on Resident Evil 5 because its heavily shader dependent instead of texture unit dependent. In other words it works better with the ATI GPU.

You guys are also missing my other purpose for this rig BESIDES gaming. I said earlier I wanted it for hardware acceleration. The four ATI cards offer 6400 shader processors equivalent of 11 TeraFLOPS single precision processing power while the 4X 480 SLI consists of only 1920 shaders equivalent of at most 5 TeraFLOPS. As of now, there are many software (Adobe) and benchmark products that benefit from this. READ BEFORE YOU POST.

You realize by attempting to compare shader counts between ATI and nVidia, you arent comparing apples to oranges, its more like comparing oranges to basketballs, yeah they are both round and orange, but thats where the similarities end. nVidia shaders are built very differently from ATI shaders and as such you cannot compare them on shader count, a GTX 480 with 480 shaders will beat a 5870 with 1600 shaders in most applications, especially Adobe apps since many of them do have CUDA support for nVidia cards.

lol? are you also implying a 4core athlon II 635(with a stock clock of 3.1ghz) beats an intel i7 950 at 3.06ghz?
October 12, 2010 3:34:57 PM

i get your reason for 4x 5870s but wouldnt 2x 5970s be better? and cheaper?

2x 5970 has less FPS and TeraFLOPS because its essentially 2 underclocked 5870s sharing one x16 lane. So like I said earlier, they are not better. Common knowledge.

even though that may be right, the fact is when going this high end(gaming or proffesional apps) nvidia destroys ati. Forget those 5870s. Either get 2 watercooled 5970s and overclock them or make the right decision and go nvidia.

I agree!!!!
October 12, 2010 6:33:02 PM

how about you get 1 workstation build for $2500 and 1 gaming build for $2500?
October 15, 2010 9:23:22 PM

This was supposed to be a discussion about the superiority of 4X 5870 CFX in hardware accelerated applications.

CUDA support or not, it is more towards raw GPGPU performance in cases such as offloading CPU workload.

yes, the 635 in this case would be the GTX 480 and the CI7 5870.

apparently not w/ 300+ FPS in Resident Evil 5

If your gpu got 60 fps you wouldnt notice a difference between the 2 setups which probably would be $4300 less than the one you want to build.

You need to look at benchmarks that actually mean something. Like crysis, metro 2033, etc etc. You'll also notice that 3x480 will scale better than 4x480 most of the time, and they usually come out on top.

In reality either of the cards in 2xsli/crossfire will handle any game acceptably. Why would you spend so much money right now? In a couple years though cards will become a joke in gaming and will be replaced by much better cards. So as mr. pizza suggested go buy some booze with all the money you'll save. You'll be much happier that way.
