hi all. i am building a system for my brother and i am undecided about which cpu to get. the cpus in question are the amd athlon xp 2500+, amd athlon xp 2800+, and the intel p4 2.4c. the 2800+ and 2.4c i can get at the same price. is that 800mhz fsb and hyperthreading worth it? i hear that the 2.4c could OC pretty good. or should i just save 100 bucks and get the 2500+ and OC that. i am unsure at what i should do. thank you all in advance.
