Quad-SLI GTX580 (Dedi PhysX) Vs. Tri-SLI GTX595 (Dedi PhysX)

post #1 of 19
Thread Starter 
For the sake of argument, lets say the GTX595 turns out to be two GTX570's (as rumoured).... Which would win?

1) Tri-SLI GTX580 + Single GTX580 For PhysX
2) Dual-SLI GTX595 + Single GTX595 for PhysX

I'm trying to dream up the ultimate machine, but stuck on which GPU config I would go with.

I wouldn't even worry about choosing the GPU's until you know what your running. Bulldozer or Sandy/Ivy Bridge, motherboard, drives, PSU, THEN look at graphics.

But between those, I would go with the Tri-SLI solution. Worst case, one card dies and your still safe. Two die? Still fine. But there is absolutely no reason to get a 580 JUST for Physx, just go Quad-SLI and you'll be fine.

That machine WOULD be ultimate, but it would be mostly for e-peen and benchmarks IMO. Nobody needs that much raw power, unless your trying to max out Metro 2033 in Surround 3D.

I would go for the Tri-setup only because scaling on quads are bad. Quad will be faster in benchmarks, but games likely won't take advantage of the hardware due to drivers.

While I do agree with what you've said. I'd say get the PSU after the graphics. Just makes more sense when it's the most power hungry part.

As I said, it's just a dream PC, so it's nothing to take too seriously.

Motherboard? Hmm... I was thinking of the EVGA SR-2 with Dual 8 Core Xeon's and 24GB's of RAM.

BOOM!

There is no GTX 595. The dual GPU card we've been seeing is an EVGA made custom card, which has 2 GTX 460 GPUs.

I thought the max support for the GTX580 was Tri-SLI and not Quad?

OK...Dream machine .
Lets be real for a little. Using a dual gpu card for physX will only utilize 1gpu. So a gtx 595 is useless for physX.
Now IF we want to dream a little bit...Id say 4-way sli gtx580 and use either galaxy's single slot 460 or single slot 450 for physX.
Then u can max out most games on 3d vision surround.

I'm trying to dream up the ultimate machine, but stuck on which GPU config I would go with.

1, you can't uses both cores on a dual GPU for Physx.
2, God knows what the specs are for a GTX595.
3, if you have four GTX580's. YOU WILL NOT NEED A PHYSX CARD!
4, Personally i would go for SLI GTX595. but i guess having 4 Graphics cards would look cool but it would have to be watercooled...
