Which is better?

[ChillBot]

What is better Athlon XP or MP. I'm looking to buy one or the other
and just want to know which is more worth my money.

MP is a dual unlocked XP and tested(?) for dual CPU systems. If you have a single CPU system go for XP, if you have dual, you could try XP and unlock, but MP will probably be more reliable.
