I do graphic design and Photoshop work. I was planning to buy a Refurbished 2012 Mac Pro 3.2GHz Quad-Core and upgrade the HD to SSD plus 16BG RAM. This will cost me about 3k. For the same amount of money I can get Refurbished 15in 2.7GHz cMBP 2012 and upgrade it to 512Gb SSD and 16GB RAM. I have two great external monitors (EIZO & NEC) which I can connect to laptop. That is the reason I do not consider iMac. Which would be more reasonable option? What are your thought? Thank you!
