Which GPU do you have in particular? the new 4600 cards from intel are pretty good (not sure if a mobile version is available).
Ideally it would only enhance the graphics but if the integrated GPU was bottlenecking the CPU, you'll get a performance boost.
You can test this by decreasing IR, if this yields a speedup then getting a new GPU will help performance also.
