That Asus has the Geforce 310 http://www.asus.com/Notebooks/Versatile_Performance/K52JC/#specifications
So the issue with setting the graphics is a common one as you see it has the Optimus tech. On my laptop I have a right click option which offers me a way to select the GPU or the Intel HD solution.
It's a shame the makers don't offer courses on this but given it's at the bottom of the GPU list (310 is...) and the 5450 is not this should level the playing field and for 30 bucks is worth the gamble.
Yes you could get a more powerful card but this may be your first foray into PC upgrading. Let's keep it cheap and simple.
