I had a Dell PC with PCIe 1.1 in which I installed an HD 5670 and it worked just fine. All modern GPUs are backwards-compatible with all versions of PCIe. Unless your motherboard has a problem, you won't.
Best card at that price is the HD 7750 - and you won't have to upgrade your power supply to run it.
No, but mine was already on the latest BIOS version (2009) when I got the PC. You should definitely flash to the latest version of your motherboard's BIOS before any upgrades, however.
If worst comes to worst, give American Megatrends a call and see what their latest BIOS is for that motherboard. They'll probably shunt you to someone who knows what they're talking about, and then you can ask about compatibility with recent video cards.
