I will be building a new rig soon, but I am a bit confused as to which CPU to go for. I will be using an Asus A7N8X deluxe Mobo, and want to get the best performace possible without overclocking. My 3 choices so far are AthlonXP 2500+ 2700+ and 2800+ But I have a few questions. Is the 2800+ worth paying an extra £80 for above the 2500+? Does the extra Cache on the Barton CPU's mean that a 2500+ would beat a 2700+, or is the extra Cache not that important? How much difference does the 333 FSB make compared to a 233 FSB CPU? Basically what I'm looking for is the absolute best CPU for no more than £200. Any comments/suggestions would be cool. Many thanks.
