Planning my first build using a EVGA 8800GT video card which I believe is a PCI Express 16x "2.0" type. I'm only going to use 1 card so don't need SLI. I know they say these 2.0 cards are backward compatible with PCI 1.0 and 1.1 but I would like to get the full performance out of it by using it in a 2.0 PCI slot. All the Mobo's I have researched using 2.0 have 2 slots ready for SLI or Crossfire. I figured I'd end up buying one of these and just leave one slot unused but many mobo reviews say if you're not going SLI or Crossfire, you're just wasting money and space going with the 2 slot 2.0's.. Anyone know of single slot PCI-E 16x 2.0 Mobo's? If not, does anyone know if I would lose much performance using it in a PCI-E 16x 1.0 or 1.1?
