Looking to update my 4-year old iMac to something with more horsepower for Lightroom, and high speed storage options. In theory the CPU is upgradable, but my i7 860 never had many upgrade options since Intel discontinued the socket in early 2010. The lack of USB 3.0 makes external storage painful. At this point, I'm deciding between getting a secondhand 2009 Mac Pro and upgrading it heavily, or building my own 'Hackintosh'. The two builds I'm considering are: Mac Pro 2009 Mac Pro dual socket (base model) - secondhand 2x Xeon W5590 CPUs (so 2x4x3.33GHZ) - secondhand 24GB RAM (3x8GB) Samsung EVO 256GB SSD Geforce 650 GTX (2GB, flashed for MacOS X) USB 3.0 card (Orico 4-port) SATA III card (Syba SD-PEX40054 is supposedly bootable) Total: $2180 (assumes Mac Pro will be around $1250 and CPUs around $400) Self-built Core i7 4930K (6x3.4GHZ, overclockable) Gigabyte X79 motherboard (GX-X79-UP4) ATX mid tower case (Antec 300) 500W PSU (Corsair CX500) 24GB RAM (3x8GB) Samsung EVO 256GB SSD Geforce 650 GTX (2GB) Total: $1485 Clearly the Hackintosh is significantly less expensive (~$700 if my calculations are correct), so the question is, aside from the obvious fact that you don't have to worry about setting it up and updating it (OS X will just run), does the Mac Pro provide any significant advantages in terms of either Lightroom performance or future-proofing?
