I have an older Dell XPS Gen 5 PC with a motherboard based on Intel 955X chipset. This chipset from what I can tell uses v1.0a of the PCI Express spec. I tried an MSI n9400GT MD512 which stated it would work with the older spec, but it wouldn't work in my system (I could never get drivers installed or the BIOS updated). I put my GeForce 8600 back in without issue. It appeared that the Radeon 2600 would be an option but I wasn't sure. Anybody have a recomendation for a v1.0 PCI Express x16 video card that will work well for an HTPC and HD video?
