Anyone else having problems with your cards? there is a topic on the eVGA forums http://www.evga.com/community/messageboard/topic.asp?TOPIC_ID=13545 I have all these issues, my card was running fantastic the first day I got it (580/1770) now if I want to play a game I have to run 500/1400 or else the game or system crashes, I have a CO card stock at 500/1500 yet it dosen't run at that or else as I said crashing or major artifacts in games.
