Depends on what you want I suppose.
I like playing games maxed out with full eye candy, can't fathom people spending thousands on a machine not to push it and get the best graphics possible and all.
But saying that, I know people who I cannot fathom, because in LAN's that I go too, there are gamers that have a better set up than mine, playing on 15" CRT's with their noses on the screen and the graphics are horrible.
They kick my rear end, but my game looks nice lol
