The HD 3470 M isn't what anyone would call a "decent" graphics card, and it is relatively old by now, as well. I can't imagine its performance would satisfy anyone. However, the worst thing about that system is the very poor CPU. Pentium Duals are the very lowest quality Intel chip after the Celeron, with the greatest majority of the internal cache RAM that added so much to the performance of the C2D totally ripped out.

(and
sufficient performance to actually put that VRAM to use) * DirectX compatible sound card

Recommended Specs (For running Skyrim on "High" settings at 1920x1080 resolution)

TTBOMK, the maximum VRAM that a 64-bit GPU such as an HD 3470 is able to manage is 128 MBs.

P. S. It is an acknowledged fact that with the kind of gutted-out nature of Pentium Dual manufacture, they can overclock easily. On the other hand, almost no one's laptop offers either a built-in overclocking access point, nor anything close to enough cooling capacity to deal with overclocking requirements.
It may be unkind to be so truthful, but attempting to pretend that this dinosaur of a laptop is a games-usable machine is like handing pigs' ears to a seamstress, and asking for a beaded silk evening purse to be made from them.
