You could possibly try going with a 7870ghz edition. Depending on the price of the card that you have right now the prices for a 7870 are going to be probably 20$ more and generally can be pushed a bit more than nvidia cards (Speaking in terms of reference cards.) The 7870 is also going to suck down a bit more juice, depending on the budget that can be an issue. But if you don't really want to spend that much money just get a 660 with a really nice cooler, like a Zotac Or Gigabyte.
