Oh if you are not going on 1080p then
Fallout 3 bare. YOU SHOULD MAX IT OUT EASILY.
SKYRIM AND WARZ really depends but You should have no problems having it at HIGH.
Honestly, having a 7850 and not being on 1080p, you will max a lot of games and most games will be at high.
BF3 will surely get to High. I've seen youtube vids that can get it up High and at decent framerates.
