I'm starting to shoot and edit lots of high resolution video, and I'm looking for my next computer. Any suggestions? I'll probably be focusing on towers/desktops for the best bang for the buck. My laptop is powerful beast, but some of these processing times are still running too long. Question: How do you compare graphics processing power between Macs and PCs? PCs are easy to rank, but I don't know how to compare the apples to the oranges in regard to graphics card and pure chip power. I don't care about anything else, this will be a rendering engine.
