I have a AMD Athlon XP 2500 with 512mb PC2700 Ram and a 40GB 8mb Hard Drive. My computer performs very well for me, I never get any slow-down, and I still have 20GB left on my 40GB. I'm not a gamer, all I really do on the computer is surf the internet, download music and video, burn cd's/dvd's. I have $75 to spend on newegg but I'm kind of torn between getting an additional 512MB ram or to get a 80GB or 120GB hard drive. I don't know how much of a performance increase I'll see with the ram but I know you can never have enough. I also know my hard drive is small by today's standards so what do you guys think i should get?
