Dual core : yes or no?

I've got around $315 tax refund coming at the end of this month, and I'm buying a new processor.  I'm leaning towards an Opteron, but should I spring for a dual-core, or not?

Because you're talking out your ass, that's why. You have absolutely no fucking clue.

a) I guess those multi-core boxen running NT4 in 1996 were my imagination?
b) It's also funny because of Vista's requirements.
c) You've obviously never programmed an application in your life. Windows apps already use piles of theads.
d) Guess what VM means? Virtual Machine! Guess what context switching is for? Switching between virtual processors and memory space.

Duuuuuh huuuuur huuuuur MS lol winnar!
