i can either get a 3200+ or an x2 3800+.
Most likely, I'll be running two monitors, with WoW on one and internet/music/whatever on the second. Though, I won't even be playing WoW every day. If this is the case, do I really need the x2 3800?
You cant be playing a game on one monitor, and browsing the web/listening to music on the other. Since games will either be extended on both monitors, or cloned. And you only have control for one mouse, so once you try clicking on a website link, you may be doing something you dont want to in the game.
But for multi-tasking, the X2 3800+ would be much better.
