I am a videographer who needs to bring my Mac Pro back from the dead. Nerdy with video files but not computer parts. My reading thus far has prompted me to look into the following. I am looking for a better understanding of each of the following and which upgrades are beneficial and worth it, and which may be over-kill for an aging tower. Memory. I currently have 4x2gb or 8gb total of ram. I know it is ridiculous I haven't upped to at least 16gb thus far. However, I have read that memory can only help so much and that some of the below elements are the real speed boosters. What amount of memory is recommended for this setup? Is this what I should be purchasing? http://www.amazon.com/16GB-DDR3-1066-PC3-8500-1066Mhz-Apple/dp/B0098MLFJG/ Solid State Drives. I currently have 3 internal disk-drives thatrange from 500gb to 2tb. If I used this as my start-up drive, where is the best place to install it (see photo below)? I have read of people installing in SATA Hard Drive Bay or in the unused optical SATA drive. I have read good things about this one. http://www.amazon.com/Samsung-2-5-I...p/B00OBRE5UE/ref=cm_cr_pr_product_top?ie=UTF8 Video/Graphics card. First, do those both mean the same thing? Are the 4 PCI Express slots below only for this type of card? Also, can you have two installed? I have the standard NVIDIA GeForce GT 120 512 MB. What is the best way to upgrade? My research so far has led me to the GeForce GTX680. It looks like I will need to buy it used though. http://www.amazon.com/EVGA-GeForce-DisplayPort-Graphics-02G-P4-3682-KR/dp/B00C81T7ZS Upgrade Processor. I'm intimidated by this one due to the intensive install and price. What would be the next best bet - upgrading to 12-core? Where to buy? Firmware?? I've seen some videos and forums about (4,1 - which I have) (5,1) or (6,1). I don't really understand what this means. Is this something I should be concerned with? Thanks!
