Wow. That's about all I can say.

Nice work.

Let me ask have you played any games with them yet? Have you experienced any micro-stuttering?

Sorry dude. Take your time.

Added some OC, fan speed, and temp numbers and observations for the solo Co-Op card.

wow... no volterra ic for voltages on the co-op.
FAIL.

Thanks for doing this. After dealing with 5 other quad GPU owners and getting absolutely nowhere....

This

is really bad.

Comparison. 4AA

You are absolutely correct, it is really bad ... because when I ran it on the Co-op alone, the scores were practically identical. My suspicion, expressed in my 'analysis' that quad-sli wasn't working on that test, appear to be true...

Did you also turn on the A-tested DX10 AA like I did on that test?

Besides q-sli not working I got something else funky going on w/that test, cause the first three tests always bog down when the camera is moving into the clear sky camp (that's where those 8-9 fps mins come in) but then on test three, the hardest one, it doesn't happen there. As we can see, on that test, our mins are almost identical.

There's no logical reason I can see why, even w/only one 295, my mins should be like 4x lower than your tri-sli rig ... unless, at that point in the test, the mem usage is shooting up over 896MB or something ... if I could get RT working in Win 7 I could check this theory, but I don't think it does, does it?

Edit: Damn, I just went through all this rigamarole to finally get RT working on 64-bit Windows 7 ... only to discover the one thing I care about right now, which is monitoring vram usage ... cannot be done in vista, apparently due to something called vista videomemory virtualization.

How friggin annoying ...

wat about the supposed microstuttering

Although this is somewhat subjective (entirely, really) I did notice that on the quad-sli benchmarks, whilst framerates were higher (except in stalker), there seemed to be a certain 'jerkiness' to the image, which seemed to be a lot less pronounced when I was running them on the single 295.

I haven't actually gamed yet on the q-sli, I'm trying to wrap up the single 295 benchies for comparison, but as you can see above I've discovered Stalker CS wasn't actually running in quad-sli before so I'm trying to get that sorted...

From what I've seen so far, I think the stuttering thing is entirely 'real' ... but i'll let you know once I've gamed on it whether it's actually detrimental to the experience.
