Hi, I just bought the new 15" top of the line retina macbook pro, and I upgraded the SSD to 1TB, but did not completely max it out and go for the 2.8 GHz over the 2.5 GHz. I have been using it for a couple of days, and am largely satisfied with it, but there is that part of me that thinks it would be just a little faster with the 2.8. I do a lot of work with Final Cut Pro and Photoshop rendering videos and such. Say I'm exporting a video that right now took 2.5 minutes to render. What would the difference be with the 2.8 GHz upgrade? Is it worth returning and going for it or should I save $180?
