Report How much performance is between a core 2 duo with fsb 667 and and fsb 800 in General Discussion Posted April 25, 2007 I found this: The smaller the CPU to FSB ratio, the more efficiently the processor can work. Therefore, faster frontside bus speeds lead to faster overall performance. When the CPU to FSB ratio is high, the processor often has to wait for data to be sent out over the system bus before getting new data to process. I should've googled it...basically your fsb needs to be higher only as your processor speed gets higher, so if intel is realeasing a 800fsb processor that means they are probably gonna go a litter higher with their actual processor speeds right? I'm glad cus i don't think i could've afforded a more expensive processor anyway.
