I'd like some suggestions for an all around graphics card maybe leaning more towards the workstation side. I'd like to do some learning of a 3d modeling program from work and AutoCAD. I'll be doing a fair amount of Creative Suite 4. But my 9yo son would probably like to play a game on it from time to time. I'd prefer to be more on the budget side. Any suggestions? I have a i7 860 system that I recently put together and a 2048 x 1152 resolution 23" Samsung monitor.
