Being the "tech guy" of the house, my brother has requested that I upgrade his 4,1 Mac Pro. He currently has: 2 x 2.26 Quad-Core Xenons 12 GB RAM 3 x GeForce GT 120 4 x 2 TB HDD's in a software RAID 10 80 GB SSD in one of the optical bays as a boot disk. He primarily uses his computer for video editing, mostly in Final Cut Pro X, but sometimes he'll dabble in the Adobe suite. So he said that he wants more speed and needs less storage; i.e., he doesn't need his main drive to be more than 2 TB. Budget is not really an issue here, but future-proofing is: I don't want to have to upgrade anything for a long time. So RAM upgrade is simple enough, right? Just head over to OWC and grab 24 or 32 GB of whatever they say goes with the 4,1 generation Mac Pro. Video cards I know next to nothing about. I don't quite understand why he's got three of them for; his only monitor is a 30 in. cinema display. Should I upgrade his video card(s)? Maybe the Raedon 5770 or 5870? I feel like video editing isn't really all that GPU-intensive, but if it is, please tell me so. Now, the fun part is the storage. I figure the best solution is get four new SSD's to replace the 12 TB ones, and stick the SSDs in a RAID 0. So the question is: do I need a RAID card for that? Or, I guess, more accurately: do I want a RAID card for that? And if I do, which one? I assume not the Apple one, as I see it's not well liked. Then I guess I could get an external RAID enclosure thingie for the leftover disks and use them for backup/additional storage. Also, do I want to upgrade the CPU? I still feel like the bottle neck for him is not in the CPU but in read/write times, but if what he has is really outdated at this point (or will be in the near future), maybe I should fix that.
