I am a little late to the party with regards to upgrading to Mavericks but now that I am I am finding my stock nvidia GeForce GT 120 is not supported in 10.9.1. I split my time between FCP and After Effects (CS6). I am about to plunge into FCPX as well.What would be the best card I can upgrade to assuming a 50/50 split btwn FCP and AE? As usual, price vs performance is important. No gaming requirements needed.
