Of coarse it will run much faster:-) With GT120 as a GUI, when you use your computer with Premiere or AE or AVID MC, the application uses GT120 as a GPU renderer. If you use GTX 480 as a GUI, all those applications, that use GPU acceleration will benefit greatly. So, for example, when I have to use Smoke, I plug my GUI into the GTX570 and then that card is used for the GPU acceleration. No computer restart required. For Resolve use, i plug back into GT120. It’s not GT120’s fault, that you’re not utilizing your GPUs correctly:-)
