How important is the CPUNB speed to performance? I know that HT speed is not that important but I assume that CPUNB is more critical since it has to do with the ICM. In overclocking my PI X3 to 3.1 ghz with the clock multiplier I have lowered the CPUNB multiplier to keep it at the stock 1.8 ghz. Is this creating a major bottleneck to performance? I guess I should also mention that I am not overclocking the fsb. It is set at 200 mhz.
