I stopped keeping up on video cards years ago & my 8600GT won't cut it with any of the newer games I want to buy. I have an older Gigabyte GA-G31M-S2L that I'm pretty sure has a PCI-e v. 1.0 slot, but want to run one of the newer ATI 5750s on it. From what I gather it'll work, at least according to Wikipedia (hehe),
"PCIe 2.0 motherboard slots are backward compatible with PCIe v1.x. PCIe 2.0 cards have good backward compatibility, new PCIe 2.0 graphics cards are compatible with PCIe 1.1 motherboards, meaning that they will run on them using the available bandwidth of PCI Express 1.1. Overall, graphic cards or motherboards designed for v 2.0 will be able to work with the other being v 1.1 or v 1.0."
Clearly, I'd like more advice than Wikipedia's before I drop $150 on a card that might not work with my system.

should work just fine. im running 2 5870s in x8 crossfire config on my UD3P without serious issue, running a single 5750 would be significantly less bandwidth intensive and should run just fine

Video cards these days are not even using up the full 16 lanes provided in the Pci-Express 1.0 slots. So you won't notice a difference between using pci e 1.0 and 2.0, at least not a very noticeable one.

I think that's gonna change with the 5970...

More so actually. There was a difference with other dual-GPU cards like the 4870X2 and GTX295. Even the 5870 shows some (although a much smaller) improvement going to PCIe 2.0.

However, with the 5750 there won't be a bit of difference. Enjoy your new card OP :)
