i currently have a Dell Dimension 4550. it's a good computer, but the truth is, it doesnt fit my needs. since my dad got it for me 2 years ago, i couldnt really ask for a gaming computer. well since i have a job this summer, i wanted to invest in selling my current computer and buying some gamings computer. i'd spend 500$ or around that price. i also want to note i ONLY need the computer, no monitor because i have a 15" flat panel. if anyone can help me out that would be appreciated.
