Hello,

I have a chance to get a Intel® Core™ i7-975 Processor Extreme Edition (8M Cache, 3.33 GHz, 6.40 GT/s Intel® QPI) for $250... I have a Intel® Core™ i7-950 Processor (8M Cache, 3.06 GHz, 4.80 GT/s Intel® QPI) now.. I do alot of 3d modeling and Cad/Cam programming... I also game on it sometimes... Will I notice a difference if I get this processor? I have 12gbs of gaming ram and two SSD drives... I have a 1366 socket mother board so it will fit.... Or would I be better with more cores processor like i7-970 6 cores....

Thanks

The 975 is unlocked which is good for overclocking, but I don't think you're likely to see a significant difference if you don't.

The 975 has slightly higher clock speed and few other slight differences but i doubt there would be a major difference in performance.
