I'm looking to build a new pc soon, and I am an amd fan, but the new line of proccessors latley have been confusing me a little. Theres the AMD Athlon 3800+ / 2.40GHz and it has 2000mhz. Now theres the AMD Althon 64 "X2" 4200+/2.20Ghz which 1000mhz, and 2000 MT/s. Which is the better processor. I would think the 4200 is, but its 2.2 and not 2.4. Also I saw a post saying that the Intel Core 2 Duo E6300 is way better than the AMD 4200. How is that possible its 1.86GHz, amd a bus speed of 1066MHz. Although is has 2Mb Cache size. But the 4200 is 1Mb I believe. So how can the E6300 be way better and faster? Which is the better proccessor, or what would be the best processor duo core, for around $215? Thanks for your help.
