I'm building a new rig and want for it to last, so the question being, which CPU can I get right now that's going to perform well for a while (in terms of performance in games, firstly). I realise that E8400 is a pretty good deal right now, but in the long run, should I be aiming for C2Q instead or should I commit to E8400 and either run with it or plan to replace it earlier than I would with a quad? Overclocking capacity definitely matters for me here. Help me out here. The video I'll be using is HD4850.
