My dad has a 2.2 celeron and it's slow as fuck. It's fine for what he does, but I would crush that weak ass chip. If you're gonna be gaming don't get a celeron.

There's prices for AMD's shit. I don't know how much you want to spend so there's all of them. Free shipping too. XP 2400+ is only $80 right now. You would be very happy with that.
