As I belive that many uf us want to try to reuse already owned or old hardware in general, but that often the Graphics performance is the issue to get UI2, this might be of interest:
The company "Albatron" will soon offer graphics cards based on the GeForce 8400, 8500 und auch 8600 FOR THE PCI SLOT.
This means that (some) of these cards will have just the ideal gpu chipset for LMCE and that you can use it on hardware without a agp or pci-express slot (or as a second or alternative graphics card). Me for example I own some Dell desktops with integrated gpu and no agp or pci-express slott....so this should just be ideal for it.
