Hey guys! Going to put my order in for the updated 15 inch retina pro tomorrow. I'll be using the education store, so it's only £68 to upgrade to the 2.5 processor. What do you think? I don't expect I'd notice the difference but in a bench mark, but only a couple of days ago these machines were 2ghz base - thinking I can get 2.5ghz for actually less money because of the price drop and with 16gb of ram seems like a very good deal! Or is it just a waste of money? Apart from all the normal stuff, I use Lightroom for Raw file editing and Garageband for recording guitar/bass and vocals. I know either the 2.2 or 2.5 would be good at it, but for £68 is it worth just getting the 2.5?! Thanks guys, I know I'm babbling but just want to get my purchase right! The 256 ssd is fine for me, I have a USB 3 LaCie 3tb drive and another drive for back up. Cheers!
