Small ? regarding PCI-E 2.0 and 3.0

[UNCDoug]

So I'm ready to ditch my GTX 465 card that has done admirably over the years, and I found a GTX 970 that I've settled on.

Question is, I have a mobo that is only PCI-Express 2.0 and of course the new 970's and 980's are all 3.0.

So my question is, how much performance should I still expect even without the 3.0 motherboard capibility? In case if anyone asks, upgrading mobos is not a possibility at the moment.

Thanks in advance.

Opps, wrong board. Sorry. Please delete.

As long as you have a 16x PCI-E slot with full 16 lanes of PCI-Ex2 then you will be fine. Current cards only need 8 lanes of PCI-Ex3, which is the same bandwidth as 16 lanes of x2.

I have two PCI-E 2.0 x16. Cool! Thank you.

What he said, cards still don't saturate PCI-E 2.0. I have a 2.0 mobo myself. Once 4.0 standard is adopted we should start worrying/upgrading, til then buy away
