no ur MB does not suck it just doesn't support SLI/Croosfire.....dontworry mine doesn't either but mine is a micro ITX. I think your best bet is to pick up a 6950 and unlock it to a 6970.
you also never gave us a budget that you would like to stay with in....otherwise people are going to assume you have rediculous amounts of $$$$ and tell you to buy a 6990 or GTX590 which area $700+ grafix cards lol
ok well i also have another question if u can answer it bro
can my amd 3.4ghz processor be removed if i ever wanted to put it on another one?
and my price budget i say would be possibly $200-$350/$400
also someone said that unlocking it would just harm it, is that true?
P.S. i wouldnt know how to do that anyways & what would be the difference?
if u can please answer all question im sorryy, but im learning (:
