Technical support megathread 2

Can anyone help me figure how to get better graphics? PC build posted below. I'm running on medium, playing with an Xbox 360 controller on a plasma screen TV. I know I should get a monitor, but I still think I should be able to play on better than medium. I haven't got the Swiftech, cause I haven't overclocked CPU. On high, the game is very pretty, but sort of stutters, where holding the controller stick to one side will move it in little steps. I'm also running the Audio/Video through HDMI on the motherboard, will change to videocard tonight.
