Ignore all of the above, the best upgrade from a 285 GTX is a 2nd 285 GTX!
285 GTX SLi
Lot of money for a 2nd card tho that would be better off going towards something with DX11 and better future compatibility.
5970 it is then
Which of the new nvidia cards do i need to get to get a decent jump in performance from a 285 gtx?
