The 7 series motherboards are bad and you wont find many people in love with the idea of suggesting one. If you must get one, then the EVGA boards tend to be the best of the worst.

Do you think I would be better off staying with one card, forget the sli (my video on my xps with one 260/216) looks great compaired to my 8800gt, and concentrate on a different board and cpu, if so which would you suggest?

My other 2 xfx 260's one is new and the other is a month old, there selling for around $200 new, so how much would I really get for them? I am not stuck on the idea of sli with the 7 series board, just have those two cards! with no home for them, )Thanks for your advice
