I used to be in the computer parts biz, but that's been six years. Assuming I get into the USAF and survive basic and tech school I will have several thousand $ sitting around and I want my own PC. I want a 17" monitor, flat screen or not doesn't matter, and a good Pentium IV capable of playing any high end game out there and running online games. Not much else (standard MS word and crap like that, but I'm mostly a gamer). What's currently the "good enough to very good" specs re: RAM, video cards, speed, etc.. How good are those $500 with rebate Dells?
