Hey guys, So one of my clients was throwing out some old machines, they were going to be recycled but I offered him some money to take them off his hands. I picked up the following: Mac Pro 4,1 - 2 x 2.26ghz (8 Core), 6GB Ram, 5 x 1TB HDD's (was set up for RAID), ATI HD 4870. Mac Pro G5 -haven't checked out the spec, I know it's not worth anything. Mac Bluetooth Mouse & Keyboard. 3 x Iomega 320GB Firewire HDD's. Aja Kona LHi -retails at $1500?! Various cables and stuff. I bought the whole lot for £100. I'm in the process of updating the 4,1 to El Capitan. What are my upgrade options? I have a GTX 770 spare, will it accept this? What is reasonable with regards to RAM within a budget? Is it actually worth upgrading the 4,1 and throwing some money at it? Would value your opinions, what are some worth upgrades I can do to the 4,1 for a reasonable budget. Many thanks in advance!
