After a nice tour of duty with my 2008 MBP 2.4/4gb ram/250gb HD I think it's time to upgrade to one of the rMBPs. I've just about reached max capacity on my hard drive so I think I'll need the 512GB on the rMBP. I'm having trouble decide between the following stock models: rMBP - 2.6 ghz - 8gb RAM - 512 gb flash or rMBP - 2.7 ghz - 16gb RAM - 768gb flash The difference is almost $800 so I thought I'd consult all of you on here. I read quite about about how it is good to time-proof the computer with the RAM upgrade. Playing with a 2.3ghz rMBP in the store, I'd imagine the 2.6 would be blazing already. My main use of the computer is as a double machine with Windows installed with BootCamp. I do a lot of high intensity flight simulating on that side of the machine. On the apple side, I do a lot of Final Cut Pro. Any thoughts? Will the difference between the 2.6/8gb ram and 2.7/16gb ram be that noticeable? Thanks for your help!!
