Hi all, Im currently using a 1,1 Mac Pro (with various upgrades), which after 8 years, am finally looking at replacing (probably a bit later this year. I'm currently tossing up between a new Mac Pro and a 5K Retina iMac and was hoping to get some opinions on the two systems. Either way I'm looking to get a Promise Pegasus2 R4 with 4x 3TB Western Digital Red drives setup in RAID 5 for storage. This uses a Thunderbolt 2 connection, so would work with either system. As for the actual machine, here are the two setups I am considering: SYSTEM A: - 5K Retina iMac - 4.0GHz processor upgrade - 256GB SSD - 16GB RAM upgrade - 4GB GPU upgrade SYSTEM B: - New Mac Pro - Base 3.7GHZ Quad Core processors - 256GB SSD - 16GB RAM upgrade - Dual 3GB D500 GPU upgrade The Mac Pro obviously doesn't have a screen, although I'm currently using a Dell 30" monitor which I could use and look at upgrading to a 4K/5K monitor down the track. The Mac Pro system above is roughly $800 AUD more expensive than the iMac and I don't necessarily need 5K resolution at the moment so I'm leaning more towards the Mac Pro, but I would very much appreciate some input from you guys. I mainly do graphic design (Photoshop, Illustrator) and video (Premiere, After Effects) stuff, along with the obvious web browsing, iTunes, word processing and watching videos. No gaming and most likely won't bother with Windows. Thanks in advance!
