I would appreciate any advice or opinions. My goal is to increase performance on after effects and video editing and rendering. Current: Mac Pro 1,1 2x dual core 3.0ghz with apple raid card (original/old), esata and USB 3 pci cards, ati 5770, 24 gb ram, 2 ssd in optical bay. Potential options: 1) do the efi upgrade, swap out raid card for newer tech sas mini 6g, increase ram to 32. Cost: approx 650.00 2) buy used imac i7 and use Mac Pro as server/external drive via gigabit ethernet. Cost: 2600.00 3) buy used 5,1 and get rid of 1,1. Maybe upgrade processors later. Cost: 2300.00 Appreciate any thoughts. By the way the efi upgrade feels slightly beyond me but I'd give it a go.
