I am in the process of purchasing a new motherboard for my PC. I just have a simple, possibly rhetorical question. Does the FSB of the processor have to match the FSB of the mobo? In other words I have a 1.8Ghz Celeron at 400Mhz FSB, can I get a mobo that is rated at 533/800Mhz FSB and still use the Celeron? If so, would there be an increase in speed going up to a mobo with an 800Mhz FSB? Thanks in advance!
