I'm a video editor for work and use the company's gear. At home I'm a music composer and take on occasional freelance video editing. I'd like more power for virtual instruments, USB 3.0 to run sample libraries on external SSD, and need to keep current with a modestly powered FCPX and Premiere system. (no 4k work yet). Currently running a 2011 MBP / 16GB RAM / 512 SSD / Radeon 6770M 1GB VRAM. Lacie TB2 Hard Drive, 27" ASUS monitor. Options: 1.) I've located a dealer with a 2015 refurb w/ 1year warranty /2.5 Ghz / 512 SSD / AMD 370X for $1800. 2.) Buy a new 2016 2.7 / 512 SSD / 555 for $2800 + $100 cables/dongles 3.) Keep my 2011 and wait for the next MBP refresh. Thoughts? I'm stuck on a great deal vs possible future proofing. I like to keep computers about 4-5 years.
