MrPink: Tell ya what, even if you are not overclocking, an Intel C2D should still be fast enough. Anyway, please don't try to get that X6800. Just slap on a E6750 or a E6850 (if you have the cash), and you're good to go. Here's a benchmark and review of the CPU you are willing to buy... versus other C2D processors at STOCK.
