We upgraded our workstations the best we could.Yeah, sure Tim Cook promised that we would love what they have for us in 2013. We can't wait for that, or take a chance that it might not be what we are looking for. What are we looking for. I'd like that Linux box we have for Mari to run OS X.
Each compositor has 48 gigs of RAM. We also upgraded to a Quadro 4000. The GPU support in Nuke is a great addition. The more RAM you have the more you can cache. It's nice having a huge amount if RAM. If nice to have GPU acceleration. It's a great experience.
The Foundry also needs to step up. When this so called "Love" that apple has for us comes out its going to run Mountain lion. Last time I checked Nuke doesn't supported Mountain Lion.
Sure we can move to Linux. If we were going to do this instead we would have done it already.
