almost 2 years ago to date I asked this forum for help with a MBP for my daughter working on her degree in graphics. As a result I got her a 2013 15" 2.3 i7 and it's worked out wonderfully so far. She started motion graphics this January so we added the 27" TB Display to her arsenal. Now my query, I'm going out on a limb here in guessing motion graphics probably would benefit from more horsepower - say an 6, 8, or 12 core CPU? So I'm researching used MacPros that I can upgrade for her. Here's my checklist: CPU unit < $700. preferably upgradable to utilise multiple displays including TB Display I can do the processor upgrades myself, so I could use some guidance as to a "sleeper unit" I can drop a higher quality chipset in. Graphics CPU recommendations. HDD set-up? Currently, she uses Adobe's CC and her MBP for her projects which meets her current needs. I want to reward her hard work with a machine that will hopefully enable her to increase her "skills" level even more and then take into the work a day world when she's ready. I'm in no position to buy a TrashCan from Apple for her. I do however, have an abundance of used Quads and Octos for sale around me on the used market. Prices range from $400 - $750 for lightly upgraded to base machines. Ideas?
