Building new system, plan on overclocking. Debating on whether to get an E8400 or Q6600. I will be mostly gaming. I realize that the E8400 is better for games now, but I would like to make this rig last longer. So, would the Q6600 really offer more future proof or by the time games and applications come out that support quad will it bottleneck the rest of the system (mainly a new GPU)?
