I know 4000+ is way faster, but people sed they've been able to overclock the 3200+ up to 2.7ghz, that's a lot higher than 4000+'s unclocked core speed. Would the 3200+ be faster than a 4000+ when it's overclocked? sure cache is still higher in the 4000+, but vs 2.7ghz how far apart are the two chips?
