I run basically the same system, but with a c2d@3.4ghz.. your main drawback is that video card... if you can bump up to even a 8600GTS... the GTS is a HUGE bump over the gt... OR go get a hd4850 since they are under 200.. that would help a ton.. in shat alot of the problem is HD access and video card loading textures for the tons of toons....
