i forgot to mention that a workstation card is going to render everything in the scene, even if you can not see it in the viewport, where as a gaming card is only going to render the viewport. so if you were doing strictly animation stuff then it is really nice to be able to move through out the scene and not have to worry about a dense section of geometry lagging up the system(if you went with the workstation card.) Im just sorta throwing out random information, but if you are working on stuff for games, it is really nice to have your rig double as a testing machine for you higher LOD's (if you have the gaming card.)
