I have a 5.1 MP (Mid 2010) 3.33 GHz 6 core with the stock video card (ATI Radeon HD 5870 1024 MB). I only use the MP for Final Cut X. I waste a lot of time waiting for renders and encoding. So I was hoping/thinking that an upgraded video card might speed up my process. Any thoughts on the best way to go about this and or best cards to get.? I use Compressor and Adobe Encoder. Thanks for your assistance.
