It's a common misconception that graphic programs require high powered graphics cards when in reality the programs are cpu based. And the i3 is superior in this aspect.
Photoshop has a couple of the filters/fx being gpu accelerated. Other than that the gpu only redraws which most weak cards can handle just fine even at larger resolutions such as 11x17 300dpi (3300x5100) as the gpu is only calculating what's shown on the monitor, ie the monitor's res. Even if he were to hook up the laptop to a 1080p monitor the hd 3000 can handle it. Illustrator has the gpu just redrawing and is even more cpu dependent as it's vector based. Premiere is an exception only if he is rendering via the gpu otherwise it's similar to PS with filters/fx being gpu accelerated and redrawing and cpu based rendering. But if render times was an issue he wouldn't render via gpu since quicksync would wipe the floor with it.
