ok so here's the deal. im the type of person that does a ton of research before i buy anything that is over $50. i have been looking over processors since im looking to invest in a new desktop system. ive been reading up on dual core, single core, 64 bit, etc. and i dont know what direction to go in. im still in school and im majoring in engineering so theres a chance that i might use a few peices of engineering software if i cant make it to the lab. i also plan to play a couple of games here and there, but nothing really big. i have been pretty faithful to intel when i would build computers for friends, but i've been seriously considering the amd athlon 3200+ socket 939 processor ($135 @ newegg). to make matters worse, i know that intel's new line of chips are coming out soon but i dont think id be able to afford them. so here's the deal; im looking for a chip suitable for my needs and in my price range, prefferably around $150, but no more than $200. is there a chip(s) that i should really look at?
