It is hard to choose but from my computer i hav now i would go with the AMD i have a amd 1.3ghz and it is rated as good as a intel pentium 4 1.7ghz so if you want proper gaming than go with the amd it is alot faster and doesnt heat up as quickly as a intel but to get the best quality gaming get a amd and a geoforce 2 64mb graphics card and 512mb of ram and add 100mb of ram to your graphics card and but in a zoom600lk fan
