I just bought the new 15 inch Macbook Pro configured with 2.6GHz. I bought it for video editing as my previous Mid-2010 Macbook Pro (non-retina) with core i5 was not cutting it. But I only notice a slight increase of speed when rendering or using the same effects on the same videos I edited with my old MBP. Is there some tweak I'm supposed to do or something? Or does the huge spec bump just not mean much? Thanks for any help.
