Well, if you did want to do a budget gaming build, I'd suggest a Phenom II with AM2+ Motherboard (so you can use DDR2, 4GB of or so) plus a 4770 or 4850. That would be a pretty good system for a very low price. Don't know what that would all come out to off the top of my head, but back in January when I built mine it was good I thought, and it has only gotten cheaper since. Not saying that is the right choice, but it may be better to wait until you can do a full upgrade than to spend a sizable chunk of money on an upgrade that will only improve performance moderately.
