Try to get a video card that has 2GB of video ram, you'll need it for some high-detail tracks.

Okay thanks. Can't I just buy more ram after getting the pc?

Video ram is on the graphics card and usually can't be upgraded.

[Jeremy150]

Yeah you can buy more RAM. But im talking about on the graphics card there is something called Video ram. You need to get a graphics card with atleast 2GB. You can't upgrade/buy more video ram.

With the FX 4100 you might want to jump it up to 4.00GHz, just for some improvement
