Yes, you can run Gears on that POS card, Doesn't mean it's good. Can you run Crysis on that card without getting poor results? Poor as in Low Settings with only about 30fps.
No, no I can't.
Did I say I could? All I remember saying its a good card for running TF2, and that you don't need a damn 8800.
Honestly, not all of us have 200/300$ to spend on graphic cards.
(Well... TBH I've never even tried running Crysis)
Even if you did you would get poor settings, Trust me on this. And really you should have an 8800GT at least and not an 8500GT. You have 4GB of RAM( which isn't necessary ) and yet you have an 8500GT which to just doesn't seem logical.
