(Quad-Core)Intel® Core™ 2 Extreme QX6700 @ 2.66GHz 1066FSB 8MB L2 Cache EM64T
or
(Sckt775)Intel® Core™ 2 Duo X6800 Extreme Edition @ 2.93GHz 1066FSB 2x2MB L2 Cache EM64T
Both are the same price, however I'm unsure which is a better investment for the long run, and what the difference there is between 4 processors at 2.66GHz and 2 at 2.93 GHz, is there a meaning to the reason the quad-core is lower?
