Mac Pro upgrading
I have an older Mac Pro that I would like to upgrade. I have a few questions to ask and if anyone can help, I would greatly appreciate it.
First and foremost, here are the technical specs on my Mac Pro:
Mac Pro = (Early 2008)
Processor = 2x2.8 Ghz Quad-Core Intel Xeon
Memory = 24 GB 800 MHz DDR2 FB-DIMM
Startup Disk = Macintosh HD
Graphics = ATI Radeon HD 2600 XT 256MB
ITEM #1
I had it in for a cleaning recently, and was told that the Graphics card is having some issues, and that it will need to be replaced within a year or so. I would like to replace the graphics card, but have no idea what to buy.
My requirements: I do photography and video editing, but no gaming.
Can anyone make a recommendations? From bare minimum card price, to middle of the road.
ITEM #2
I have three internal backup hard-drives. Those three hard-drives are in addition to the main hard drive that the operating system is working from. I would like to replace these with new ones since two are no longer working already, and I'm not sure how long the third will last.
Can anyone recommend hard-drives I can purchase to install to replace the two dead ones, and update the third one that is 12 years old now. Preferably hard-drives with a minimum of 2TB each.
ITEM #3
I can't upgrade my OS past EL CAPITAN, and I presume it's because my processor is dated, probably, in addition to the Graphics Card being old, too.
My question is, can I upgrade my processor chip, or do I need a new motherboard? I was told that Mac Pros don't allow one to upgrade the motherboard. Is that true?
Any advice and help is greatly appreciated.
