as u see in my signature i have a 2600 i overclocked it .... gives me better fps and alot bettter windows performance wise.... i get 30 - 100 fps in cs:s
cause i'm running everything on full including 1280x1024 exept the water reflections those are medium eventho it says 30 fps somtimes i dont feel it it still runs smooth so... lol u hsould jsut overclock that bitch and buy a better cpu fan like i did lol
