2x GTX 670 running on PCI 2.0 x8 - Will PCI 3.0 at x8 or x16 improve performance?

[davidst99]

Hi,

I have an Asus lower end motherboard. I'm running two GTX 670 on PCI 2.0 x8 slots. Will running them on a motherboard that has PCI 3.0 with x8 or x16 slots improve performance? Thanks.

Simple answer: No

Non Simple answer: Some apps may see minor improvements, nothing worth swapping a board for.

Ok, thanks for the information! That will save me some money then

It will, but not by much. It won't increase the performance enough to justify the purchase of a new motherboard.

What motherboard are you using? Are you sure it's not x16/x4? You said lower end, which is why I ask.

Hi, I have the Asus Z77-V LK. The manual says it can run x16 PCI Express or dual at x8 mode.

Maybe a couple % in certain situations, but I wouldn't worry about it.

That's a PCI 3.0 board.

You're running at full speed already.

It does not matter.U will only gain about 2 to 4% improvement nothing more than than that.

With two 670's I went from 2 slots at pci-2.0 X8 to Pci-2.0 X16 slots. The only thing that improved was maximum FPS but nothing else. Instead of 130fps at max I got like 150. Mins and general FPS didn't budge one bit. I guess the extra bandwidth allowed for more max at the very top end but it didn't matter at all.
