I also have a video card question. I am using a xfx radeon 6970 graphics card at the moment, I have the option to upgrade and add another xfx radeon 6970 graphics card and run crossfire for cheap. Sketchup runs fine, but I don't want to spend the extra money on an extra graphics card if I don't need too. However I would like to start using rendering programs like Auto desk Maya to give some polish looks to some designs. Do I need the extra grunt for these sorts of rendering programs? I have no experience in this area so any advice will do.
