The new 2010 i7 and i5 MacBook Pro’s feature two graphics cards, an integrated Intel HD card and a GeForce GT 330M. There’s nothing wrong with this, unless you’re trying to conserve battery life and aren’t playing games. For whatever reason Apple hasn’t released any updates with the functionality to switch between the two manually, but thankfully some hackers have done the dirty work for us.
You can download gfxCardStatus here. Once installed you will find an icon in your menu bar with 2 options, ‘i’ for the Intel card and ‘n’ for the nVidia card. Have fun!
