I'm building a new rig at the moment and need a hand with processors. I'm looking at Intel i3 and i5 processors and wondering, is there a point in paying more for a quad core i5 when the dual core i3s have hyper threading? Would there be a difference in real-world performance? Let's assume I'm usually running a game (SC2, WoW, TF2, etc), Teamspeak, Winamp, some messenger program and maybe Firfox with plenty of ram.
