Hi there, I'm currently on a MBP 2011 with 128 ssd and 8gb of ram. I'm editing 4K footage of my Lumix GH4. On the Macbook it's not going so fast and I can't use Da Vinci Resolve for color grading. So I've found a second hand Mac Pro from 2007 with these specs: Mac Pro 2,1 Quadcore Intel Xeon 2 x 3 Ghz 12 GB Ram 667Mhz DDR-2, ATI Radeon HD 5770 1024 MB Videocard 256 GB Solid State Drive (system) 3 x 1TB HD. (storage) Optical Drive. The price is 875 ($ 1.075). My question is, is this worth buying? Will this Mac Pro handel the 4K better than my MBP? Currently it has Snow Leopard on it, but I'm looking to get Mavericks on it so I can use Final Cut Pro X. Thanks in advance!
