Sadly, neither the HD4000 or the 610m will give acceptable frame rates on the latest games on the laptop's native resolution (1600x900), and will struggle with most games even at 800x600. You can check the link on the HD4000 I provided.

For $180 more, you can get this laptop with i5 and two 650m's in SLI, $809. It will run most of the latest games on medium ~ medium high on 1080p with acceptable frame rates. Also has good speakers and nice looking red backlit keyboard.
The main important thing is this option will last you many more years down the road while making games look better without spending too much money.
