Does the video card play an important role in the overall performance experience when painting digitally? I'm about to upgrade my system which has a basic home/office video card. I'm planning on getting some additional memory but I'm not sure if a better video card would buy me anything. I don't do any 3d stuff, just Painter 12, Photoshop Elements and Sketchbook Pro.
I occassionally notice lag with larger brushes or when I'm using a lot of layers. Could the vid card be a factor?
Oh, I should also mention I'm getting a second monitor.
