I got some logitechs Z-640 at christmas and i've almost never use 5.1 so I'd like to know which games can handle 5.1 sound. So far I've played a few games that support it; Call of duty, UT2K3, Painkiller demo and I also think Rs3:Raven Shield got it because it sound's great. Anyway I just wanted to know if some people know other game with 5.1 or just greater sound than average. Thanks in advance .
