What's a decent replacement for my EVGA 285? Running I7 920 oc to 3.3, 6GB DDR3, 1000 watt ps, Antec gaming case with lots of heavy duty air cooling. Used to SLI on previous pc but retired and can't spend like that now. Still a gamer. It's October 2012.
500 could get you an overclocked GTX 680 which is a great card but definitely has a premium to get small improvements over a GTX 670 or a 7970. If you have the money that is the card to get but if the budget is tighter at all (like hiding the dough from your wife) a GTX 670 or 7970 are great cards and will save you cash. Deciding between the two kinda depends on what games you play.
EDIT: Agree with ricardois, I have the GTX 680 and it's a great card and would choose that if you are good with spending the money.
I would look at the 7970ghz edition or the 680gtx. Look at benchmarks of games you like to play and see who comes out on top. Both companies have new BETA drivers though, so look for benchmarks that have been done in the last couple of days. As far as I have read, the 7970ghz is the fastest single gpu card available for the majority of games.
