I want to replace my current laptop with a Powermac since they are a good price and run Mac os x. I am planning to use a HD Pvr 2 with the powermac , so will it work? It is a usb based device and I am recording in 1080p. I will upgrade my video card if needed. I also am gonna use Premiere Pro but since support for cs6 is gone (and 5) I plan to use something else. Is Final Cut Pro good substitute for Premiere? Also is Song Vegas supported? Last of all, what are the newest games for G5s? Would love to run GMod and HL2.
