Yeah LeJerk, I'm assuming you have the great but outdated Intel socket 775 when you mentioned duo-core2 on teamspeak last night. I had one too for years but new it was time to upgrade everything in June 2010.
This is what I would do if I were you. If you got the coin, go Intel. You can't beat it. You don't even need an i7, just an i5 (i5 has no hyperthreading), unless you use programs that utilize it.
If you don't got the coin but enough to still put a pc together, go amd. AMD is slower but a LOT cheaper. It's still pretty good stuff.
