Hi, I was wondering if I got an Intel Core 2 Duo at 2.6ghz, is that 2.6ghz PER core (5.2 ghz total), or is it the total for all of the cores? Thanks in advance.

it is 2x2.6 ,but not really a total of 5.2 as each core works independently of each other , also make sure you have more than 1 ram chip as each core will perform better with its own stick of ram,or something like that .so 2 gig ram at least .2x1 gig for best results or even 2x2 =4 gig
