I recently inherited a Mac Pro 3,1 (2008) with a 30" Cinema Display from work . Up until now I've been using a 17" Macbook Pro 2009 as my primary computer, but it died a few weeks ago and I don't plan on purchasing a new computer for the time being. Since the Mac Pro still runs well I decided I might as well make a few upgrades to it and get as much life out of it as I can. The specs that I got the computer with are: CPU: 2 x 3GHz Quad-Core Intel Xeon Memory: 20GB 800MHz DDR2 GPU: NVIDIA GeForce GT 512MB Storage: 512GB Samsung 850 EVO SSD for main drive, lots of internal and external spinning disks In the mail already is a WIFI ac / Bluetooth 4.0 Card, USB 3.0 PCIe card, Blu-ray Drive, and PCIe SATA3 adapter for the main SSD. Aside from the basic day-to-day stuff like internet browsing and watching movies, I plan on doing web programming, using Adobe Creative Suite (Photoshop, Illustrator, Lightroom, and InDesign mainly), and using Final Cut Pro X and Motion if the computer can handle those programs. I also have Windows 10 installed on Bootcamp, so being able to play newer games would be a plus (I'm not much of a gamer, but I do play occasionally). What I'm wondering is, how much benefit will I get from upgrading the graphics card? Will the slow memory and older CPU be a bottleneck that negates any performance boost of a GPU upgrade? With Final Cut in particular, I'm hoping that I'll get a big performance boost since so much of the app is GPU accelerated, (also hopefully I'd benefit in Creative Suite from OpenCL) but I'm not sure if this is a correct assumption. FWIW, I don't expect to be working with anything higher than 1080p footage in FCPX. I've looked at a number of different Nvidia and AMD cards, and I'm currently considering the AMD RX 4xx series, probably the RX 470 since I'm a bit concerned about the extra power requirements on the RX 480 running off of the internal PSU. From all reports I've read, the 470 seems to be working fine in macOS with a couple modifications (I'm fine with having no boot screen). The RX 460 is also another (cheaper) option. I realize that this machine is super old, so I don't want to over-invest in it. On the other hand, I think I'm likely to upgrade to a Mac Pro 5,1 somewhere down the line, so I figure I can always reuse the GPU that I buy. Or, I could probably use it as an eGPU if I got a different/newer Mac. With what I've spent so far, $175 USD for the RX 470 would put me around $350 all-in, which I don't consider too bad. I'm sure I could find a more powerful used Mac if I spent a bit more, but I'm liking the flexibility that a tower affords. Thanks for any suggestions!
