PCIe 2.1 and PCIe 2.0 should be backwards compatible with PCIe 1.0 but as you have noted some ATi cards don't seem to want to play the game, Nvidia cards don't seem to have the same problem though. :whistle:

I'm in the UK so I deal in £'s (sterling) and cards are priced a bit more expensively over here.

I'd go for a PCI-E 2.0 card as some PCI-E 2.1 cards have been known to cause problems in PCI-E 1.x slots.

My fave card of the moment is the GTX560Ti, for somewhat obvious reasons. :whistle:
