HD 7500G gaming performance as compared to Intel's HD 4000 (Ivy Bridge

Hi,

I'm planning on getting a Samsung Series 5 (NP535U3C) and though it's mainly going to be a media-consumption device, I plan to also use it for some light-weight gaming such as Left 4 Dead 2, DoTA 2, etc.

Do note, I'm not looking to play these games at high settings - though of course the ability to play at higher settings would be nicer.

How do you think it would fare, especially as compared to Ivy Bridge? Because I know the games I play are at the very least playable using I've Bridge.

TIA!
