Have you overclocked the CPU at all? Being that it is a black edition, it has the capability to overclock rather nicely. If you have any experience with overclocking, you're ahead of the game. If not, you may want to begin with monitoring your temperatures and deciding if your current cooling can handle more heat.
I would recommend upgrading your CPU cooler, then slowly beginning the overclocking process until you reach a high enough stable OC to appease your need for speed ;)
