I have an old Intel Pentium 4 right now. Its a bottleneck and i have got to get rid of it. I can get a GREAT! deal on a sempron 64 3100+ and a Radeon X600pro right now. I was wondering how much better would this system be than my curent one. Does anyone run the sempron 64? if So is it as cool and quick as reviews say?

current
pentium 4 2.0Ghz
1GB PC3200
Radeon 9600xt AGP

AMD Sempron 64 3100+ 1.8Ghz
1GB PC3200

I was hoping someone could have given me some advice... :(
