I guess I would benefit if I upgrade to 4 GB of RAM in my system when playing Crysis Warhead, it lags to about 3 FPS in some places but originally Crysis ran just fine with everything set to Very High. In Warhead when running everything on Enthusiast but lowering Objects of Detail to Medium i.e. less detailed textures i.e. comsumes less Memory, Crysis Warhead runs fine but it's very blurry compared to the Max settings. I run the game at 1280x1024. My question: 2x1 GB runs at CR1 but 4x1 GB would only run at CR2 but still Dual Channel, am I correct?
