You should be able to play this game on high settings, unfortunately this card will not play at ultra, but it will depend on the rest of the machine to make sure you will get these settings.
For what? I'm telling you, you'll have no problems running games with that 660. If I can do maxed settings with a 5850 then you can be assured the 660 will perform better.
If that response was for Metro2033, then yea it's because the MSAA option on that particular game kills even the best video cards like I said before. You don't even need it though. If it's for BF3, I can assure you (as the CPU thread I posted before) a 660 will max that game out.
