Simple and easy question. Buddy wants to sell a P35 board cheap that supports 1333 FSB and I just picked up a 775 quad core and I have my heart set on a 5850.

Problem is P35 only supports PCI Express 1.1. Is PCI Express 2.0 needed for the 5850? Thanks.

I guess I should have been more clear. Any speed differences between 1.1 and 2.0 using a card like the 5850?

Maybe a 4-5% difference. As far as I know, PCIe 1.1 x16 lane is close to PCIe 2.0 x8 lane.
Likely you will lose a couple fps here and there, but not likely you will notice much.

Not as far as I can tell comparing benchmark scores with P45 boards. You may gain a few FPS but apparently the difference is not really noticeable. That is what I have gathered from reading posts here.

That is awesome. I figure there was not much for full out benchmarks since PCI Express 1.0 was tested against 2.0 like 2 years ago.
