I bet half life and maybe even half life 2 would work with low settings. Half life games are really fun, and counter strike is made by the same company, and it is fun too. Counter strike (the first one) would probably work fine with normal settings, while counter strike source would probably work good with low settings.
I like racing games, and my favorite racing game is colin mcrae rally 2005. It has good graphics, and you can play on normal settings probably.
I never played quake or unreal tournament, but people say those games are good. Fear Combat is free, and it might work with low settings.
A good thing you can do is go to gamespot.com, click the PC tab, click all games under that, and then scroll down the list and click "Browse All Games." Anything released around 2005 or earlier should work good. 2006 might work good, but 2007 may be pushing it.
I doubt you will be getting bioshock or DiRT to work with the 10v
i forgot Grand Theft Auto. I totally love those games so much. GTA 3 would probably work great on the 10v, but GTA San Andreas will be slower. With GTA SA, you probably have to turn the settings down most of the way. With most games, you have to reduce settings, but who cares as long as the story is good. Even with the lowest settings, the games still look fine most of the time.
