I am switching to Mac Pro and Final Cut Studio (from PC and Adobe Pro). I'll order a 2.8 x 8 with 8800; will have about 10-12GB RAM and RAID 5. The system will be used to edit videos (not play video games). In fact, I'll be getting a 32" or 37" 1080P LCD TV as my monitor. Just wondering - will the 8800 make any difference in my case?
