nvidia 980 @ pcie 2.0 x8

[davegl1234]

Hi,

I fully appreciate the cards were only released today, so no one knows for sure, but from looking around it seems the last generation of cards are not saturating pcie 2.0 x8, e.g : http://www.pugetsystems.com/labs/articles/Impact-of-PCI-E-Speed-on-Gaming-Performance-518/

And seeing as the 980 is a slight performance increase from the last gen, I would imagine the performance hit of pcie 2.0 x8 with this card would be also minimal, right? Would you guys reason likewise?

I'm thinking of SLI'ing two of these (hoping to not upgrade my gpu again for three or four years), but still have an i7 2700k @4.6, so no pcie 3.0. Would be gaming at 1440p.

Thanks for any opinion on this

you will be fine, at most 1-3FPS you can lost with SLI 980s at dual x8 (more or less in the same line as 780TI) so no worries...

Cool, thanks, was hoping so

if its pcie 2 @ x8 would make the latency high you would experience little hickups overall but very minimal.

Yeah I read something in Maximum PC a few months back that it makes little or no difference it might 5 years from now or something. Kinda like High frequency RAM doesn't make much of a difference.
Unless it's the new DDR4.

Yea , they made the pcie 3 story to make new sale lol . Overall no major improvement .

"Two PCIe 3.0 GPUs running at x8 each on a PCIe 3.0 motherboard should have nearly the same bandwidth as two PCIe 2.0 GPUs running at x16-"
"The doubled bandwidth of PCIe 3.0 x16, compared to PCIe 2.0, doesn't seem to make much of a difference yet. AnandTech's Ryan Smith tested two Nvidia GeForce GTX Titans, the current fastest single-GPU cards, in SLI on both PCIe 3.0 and 2.0, and found, at best, a seven percent performance improvement at 5760 x 1200".
