Lenovo Y40-70 graphics working terribly

Bought this laptop from newegg a few days ago.

Of course, Lenovo ended up lowering the price of their brand new Y40-80 to $599.99 right after I bought this one (and it has better processor), so I'm even more tempted to return this one.

Graphics are working awfully on this computer. Games are somewhat laggy when they should not be at all. All drivers have been updated and updated correctly.

Dxdiag:...
