Hi,
It's nice Graphic Card. I think you can play that game with Sparkle GeForce 210.
On Nvidia 6600 GT we have 500 Mhz core speed, on 210 we have 589 Mhz, which is better. Sparkle use DDR2 memory, 6600 use GDDR3, that's why you should not buy Sparkle. Your choice now. Check this two links and compare your graphic card with your money :
