So I do Premiere Pro and After Effects, and I'm trying to figure out what is the best configuration for my Mac Pro 2009. Here are my ingredients: 256GB SSD 6g 4x1TB HDD 6g 128GB SSD 6g External HDD RAID 0 eSATA 3g PCI-e SSD card with eSATA port 6g nVIDIA GTX 570 nVIDIA GT120 So with that what is the best setup knowing that I would like different disks for OS, Media files, and Cache files. There are only 4 PCI-e ports on the machine and the internal controller is SATAII so that max speed is 3g, only the PCI-e card can do 6g. Also the GTX 570 does not have a boot screen so I might want to keep the GT120 in. I'm open to any proposition of new things to buy in a reasonable price range to make the system better. Any chance I could edit 4K with a system like that?
