Re: 600-700 budget gaming comp
dang... a screen too? what kind of screen are you thinking of? a nice Samsung 24" or a little dinky 17" off brand? the screen can eat up $200 easy if you want a good one, that leaves $400 - $500 to build a computer with... my graphics card cost more than that.
heres one thats already built and looks like its getting good reviews. i dont think you will be able to build one much faster than this for cheaper...
