If you are looking for the best integrated graphic core in a Core i5, then that would be the Intel HD 4000 in the Ivy Bridge series. While around 40% more powerful than the older Intel HD 3000, it is only around as powerful as a desktop Radeon HD 5550 graphic card. Good enough to play most games with a mix of low & medium quality graphics at 1366x768 resolution with decent performance. Unless of course the game has really demanding graphics like Metro 2033
