I have been using AMD processors for the past four years now. I'm in the market for a new system, but now I am really confused. I only hear positives about the pentium 4 and the athlon xp. I keep hearing that generally the athlon xp is the "faster" processor (im not talking mhz). I mean, when it takes the pentium 2.4ghz to beat an athlon xp 2100 (1.7ghz?), I'm not sure what to think. I am attracted to the fact that the pentium 4 processors run cooler, but then I would be tempted to overclock my processor, meaning my system will just be as loud as an AMD system because I would need cooling for overclocking (right? tell me if im wrong). If I get a P4, at the moment im tempted to get a 1.8a, and the MSI 845 Ultra ARU motherboard. Is that a good choice? Would I only need PC2100 ram, or would PC2700 work, and would it provide any advantages? If I decided to go with the athlon xp, I will probably wait until the thoroughbred pops into the market, and then price will be the determinant of what I get. Thanks all
