If you are looking for a integrated graphics solution, then AMD Llano A8 series would be the best choice. The integrated graphics core can be Crossfired with up to a Radeon HD 6670 for a little better performance. Anything more powerful than a HD 6670 will cause the integrated graphics core to shut down. Llano's CPU core is a little weaker than a Phenom II core, but is sufficient to play games.
I believe the graphics core in the Llano A8 APUs is about as powerful as the Radeon HD 5570 or HD 6570.
