Sorry I saw this late, but I hope this helps out.
I found a BFG 8800GT OC 512MB card for a great price and a great rebate. The thing that is different about this is that you can get 2 cards and 2 REBATES for $30 a piece. 2 of the same cards and a rebate for each one. That is a $60 total rebate to allow you to get a new game.
Check it out.
