I've read thru many pages of this thread and tried to search but was unable to find an answer to... Will PT LE 6.4.x work with a Core 2 Duo system (E6750)? I know that you could not use Hyperthreading with 6.4.x and assume that a true dual core cpu would cause the same issue. Has anyone got this to work? Am upgrading to core 2 duo and want to know if I have to upgrade PT as well. Thanks, Sean
