I'm looking to buy a processor for a VALUE computer that will NOT be used for games. I want at least an athlon 1700 (i will not be overclocking ever), but for $9 more i can get an 1800, for $23 more a 2000, etc. I'm hoping to keep the computer cost under $500, and right now i have a full system for ~$470 w/ an athlon xp 1700. should i get a better processor? Which athlon xp is the best performance/dollar
