Hey all, getting an editing machine - yes I know it's not a Mac Pro, it's boss's decision to go with an iMac. The question is this: Would Final Cut Pro see a difference between the 1GB vs 2GB graphics card? I will be getting FCP X when it comes out next month. I just have no idea how the program uses VRAM in a way that will affect performance? It will be 1080p footage - currently converting to ProRes codec since FCP7 sucks at AVCHD, but will use AVCHD in FCPX. Other specs: 27" iMac: 3.4Ghz Quad Core i7 16GB RAM (4x4GB aftermarket) 2TB 7200rpm HD ADM Radeon HD 6970M 2GB? GDDR5 Please reply only if you truly know what difference it will make and why. There are a lot of theories out there, and I don't want to make a purchase decision based off of that Thank you!
