nah man, there's no way the cards are *ahead* of the curve.
No pc I've seen can run ut 2003 max res, max detail, 8X AA 8XAF
they've still got plently of room for improvement. If you want to buy a card for that game, but it just before the game comes out. That way you'll be able to see all the cards availible and make you choice then. There's going to be new cards between here and there meaning that A) there's more performance coming B) the card's ure looking at now will get cheaper.
Just sit tight is my advice
