PCI-express 1.1 and PCI-express 2.0 are standards for board utilization. 1.1 means that only one slot can run at x16. The rest will be downclocked to 8x or 4x or whatever. PCI-X 2.0 means that two slots can run at full x16.



Your specs don't get reduced like that. Your 9400GT would work just fine, just so long as you weren't trying to pair it with something else.



If you're only using one card, the PCI 1.1 or 2.0 are irrelevant, unless you plan on doing SLI or Crossfire in the future.



(EDIT)

I'd start with either the HD4650, HD4670, HD4830 or an nVidia alternative would be the 9400 or 9500. Anything more would be overkill. Just run your resolution at 1280x1024 or 1600x1200 (if your screen can handle it)
