Is it possible on a MBP? I have a '10 model 2.66 core i7 NVIDIA GeForce GT 330M 512MB. I'm starting to do more video work and it's not holding up as well as I'd like. I just ordered an iMac to handle the bulk of the load. I will have times where I'm shooting in the field and would like to be able to do quick edits with 4k footage. As it is it can't handle 4k. Thanks.
