Hi I am confused. I have an Asus P5N32e-SLI MB it has 2x PCIe x16 slots. I have read that PCIe 2.0 is backwards compatible. Does that mean I can upgrade my video card to a ati 4870 using PCIe 2.0 or I would need to upgrade my MB to have a 2.0 slot Thanks in advance
 
im running my 4870 on a p5n-e and its working fine.

pretty sure its not limiting my bandwidth at all. at least not for this generation of cards.

PCIe 2.0 motherboard slots are backward compatible with PCIe v1.x. PCIe 2.0 cards have good backwards 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 v2.0 will be able to work with the other being v1.1 or v1.0.

PCIe devices will connect at 1.0 speeds and then negotiate up to faster speeds. The only reason it wouldn't work is because the device isn't built to spec.

So you should be ok.
