If you're hitting 80+ degrees, your CPU is going to throttle to keep the temperature down. This is likely to be the cause (or at least a good contributor) of the large buildworld times you're seeing. You might want to look into improved cooling, possibly water-cooling. :-) Regards, Andy > Andre Guibert de Bruet | Enterprise Software Consultant > > Silicon Landmark, LLC. | http://siliconlandmark.com/ >
