i'm a Q6600 user too. but i saw u hving a gigabyte UD3P. nice one u hv

slow startup on vista?? did u try dis trick before???:

click Start.below 'All Programs' there theres smtg like a text box rite(written there 'start search'). at there, u go type msconfig den hit ENTER key.when promp for permission, click 'Continue'. Then, 'system configuration' window come out. u can see 'General', 'Boot', 'Services', 'Startup' and 'Tools' tab. u click 'Boot'. there u can see 'Microsoft Windows Vista ....' highlighted. den u click 'Advanced Options'. den u can see 'BOOT Advanced Options' window. inside there u go tick the 'Number of processors' checkbox.den it will unlock the options for u to choose the numbers. Since u're using Q6600, choose '4'. Click OK. if prompt u to restart pc. go ahead. see whether can shave off abit of ur boot up time or not. i tried and it works.

some ppl wif Q6600 need bump a little bit on vcore to achieve 3ghz especially on newer batches. for TS case, temperature already quite high, if bump up vcore, its not good for temperature. i think bump up FSB the highest as possible to pass 100 IBT runs(50 is not enuf since i get random crashes in games once in a blue moon) without hving increasing vcore is a better solution.
