Re: What's the difference between Opteron and Athlon?
WEll, opteron's are massive server cpu's. Dual core's are just regular user ones, but the 4800+'s will do a similar job to the opteron's. If the price isn't too much different, I would so go opteron's, although the architecture of the 4800+ will probably fair better in games.
Macbook Pro and Logitech z5500s. All you really need.
