I have a MSI 790FX-GD70 that is supposedly capable of 2 slots @16x or 4 slots @8x, but when i throw 2 xoc'd diamond 4890's they are listed in gpu-z as 8x, both.... i know it prolly wont make much of a diff. but i'd like stuff i spend money on to work.

Your not going to hurt it really. I doubt your losing more then 5 fps if at that. You can just test it both ways and see if you think your losing to much but no cards use up the full x16 anyways.
