GTX 260. It isn't that the GTX 460 model itself sucks, I think I just have a bad card and am going to return it. It locks up constantly. In the bios, during post, windows welcome screen, sometimes 2D desktop. Furmark locks up or drops down clocks after less than 2 mins. I need 1.06v just to hit 820mhz NOT stable. This card is a joke and a real pain to work with as its so finicky to keep from locking up on me.
