Many thanx for all the replies, Im was running 2x HD4870x2's and now im running a GTX480, so can i presume im ok with everything? And was it a wise decision to move graphic cards?
Once again many thanx
The Asus Crosshair IV Formula is a 'Crossfire' motherboard, meaning that you may combine multiple ATI/AMD video cards. The GTX480 is an 'SLI' card and multiple combinations will not work.
If possible, an HD6970 (or HD6950 2GB 'reference card') would be a better choice -- and would consume 80-100w less than the GTX480.
