I fealmretarded cus I need to get a video card, a GOOD videocard, there all pcie x16 but I only have PCIe x8 on my motherboard, how exactly can I get a good videocard for my unit
its not a problem, just plug it in, there is only a small effect dropping from x16 to x8 at the moment, next generation might cause problems but we've been saying that for the past few generations.
If you had a PCIE slot that ran at 8X it would be fine (ie a PCIE 1 x 16 slot runs like a PCIE 2.0 slot but at x8) but the xX refers to size as well as speed.
OP, is it a physical x8 slot or an electrical one? If it is physical, does it have an open end to it or a closed end? if open then it'll fit, otherwise you gotta look for a smaller card.
