Will the GTX 280 suffer performance loss on PCI-e 1.0?

I jsut ordered a P5K-E board with a p35 chipset. I found it for 99 dollars on sale at frys and picked it up. i am waiting to finish building my system when the new cards come out next month. I was wondering if it will hurt the performance of the card since the board isnt pci-e 2.0.

no u should be fine the 9800gx2 doesnt even require pcie 2.0. the new cards coming out r going to be like maybe 20-25% faster so it might use the full bandwidth of x16 but it shouldnt require pcie 2.0. u might get a few fps difference but it shouldnt be a real bottleneck. the only bottleneck i can see is the cpu these days u need a high end cpu to fully utilize high end cards. the next gen of cards i think u would need a cpu over 3.0ghz to get the full potential.

^^ well it depends on the game really, anyways it won't hurt the performance either
