I am about to order a new comp and I know that I am going to get the Dfi lanparty ut nf3 mobo. I am leaning towards an athlon64 3000+ cpu. I am also going to use the thermalright xp-120 heatsink so that I will have sufficient cooling for Overclocking. Given this information would you recommend the 3000+, 3200+, or another cpu that I have not mentioned.
