Cant believe that Mac Pro will going to be 5 years old computer already in 2018. I have classic Mac Pro 2010 with custom parts. It is not that satisfying due to the performance for Adobe programs like lightroom and photoshop since I usually handle large amount of files and each files are quite huge. Yeah waiting for one image is quite time consuming but still happy to have it since I got Mac Pro for just $175 from school I start worrying about the power supply which might gonna die soon. I could get a power supply separately but I would require to get better Mac pro within 2~3 years. Of course that I can not afford the next gen Mac Pro 2018 or later. Mac Pro 2013 seem to be quite cheaper than before for both used and new items. Btw I do mostly for photography and rarely for video. I already have Adobe RGB monitor so iMac is not an option to me. for $3~4000, will it be worth it to get Mac Pro 2013 in 2018 for my uses?
