earlier i also i used to have xp 2000+.. but shifting to intel.. u'll see a significant change...
now.. if given a chance again..o'll definitely go for intel
Yet another Intel Fanboy! You do know that AMD don't only do Athlon XP processors don't you?
This is clearly not an Intel/AMD problem, the thing is it is really not worth upgrading from an XP 2000+ to a 2400+ (unless you acquire one free), I'd save your money and put it towards a whole new PC, any new computer will be faster than what you have (even the cheapest ones).
And depending on your budget, it could be better to get AMD or it could be better to get Intel.
