I am upgrading the cpu, motherboard and ram in an old Dell DimensionXPS R450 and keeping the hard drive and floppy. Anyway, I was wondering which of these two CPU's Athlon Xp 3200 socket A or Semphron 3100 socket 754 is a faster and better buy. I will not be upgrading this system to 64 bit so having a 754 socket motherboard is not required. I just want some extra speed over my P2 450. I was just wondering which of these two is faster because they are basically in the same price range. I use this computer mostly for the internet, word processing mostly and just some light gaming. Your input would be greatly appreciated.
