I really think you need to do some homework:

The first thing you should look at is "Bandwidth (GB/s)", that give you a good rough instant guide to what the card is like. If it isn't more than 30GB/s, then forget it, the game ain't gonna even run.
If it's a card with DDR2 going through a 64 bit bus, forget it. You need GDDR3 going through 256-bit bus or GDD5 going through 128 bit bus.
A 4650 or a 5670 might get you by.
