Quick PCIe Question

post #1 of 11
Thread Starter 
OK, so I'm looking into the ASUS P8P67 Deluxe, and I see it has 3 x16 slots. I'm considering running Tri-SLI, and my question is this; can I run 3 GPUs in x8/x8/x4?

I know it's not directly answering your question, but what cards are you looking to use? I highly suggest 6990 and a 6970 for trifire. It'll outperform for the price point.

No you cannot run 3 nvidia gpu's on that board. It only has two pci-e slots that run at x8 x8.

I was thinking 2 560Ti's if it could run only 2, and 3 550Ti's if it could run 3 GPUs.

You can run SLI and Quad SLI, but only with selected cards (GTX 590, GTX 290, GTX 9800 GX2)

No Tri SLI on this mobo, sadly. You can do Trifire because trifire can work when the PCIe lanes come from different places (the third slot comes from the SB, and the first two come from the processor) while SLI must have the lanes on the same places.

Thanks! Dual-SLI it is.

3 550Ti's wouldn't be the best choice. 2 560ti's are great, though!

You can do Dual SLI+PhysX too if you wish, even tho a good card, like the 560 Ti, don't really need them (especially on SLI), or if you would like to go Radeon, you can go Xfire+PhysX. That is usually the reason the third slot is used.
