text: computer.. faster how? i have a dell optiplex gx150 tower pc:  it has 1.10 ghz processor 256 mb ram 20 gig hd (c:) and an external (usb 2.0) 200 gig hd. ati raedon 9250 graphics card wireless ethernet.   is there anything i can upgrade to make games faster? ok, the graphics card is pretty slow. but i would suggest, don't spend any dollar in an upgrade, it's useless because it makes no sense to upgrade an old p3 machine. use that pc as long as you can and save up for a new one.
