Hindi pa ata best of both worlds yan, Master Jamy. Kasi mas mabilis yung integrated ng AMD Llano sa HD64xx eh (though the HD64xx is more capable than Intel's integrated solution).
The Llano integrateds have an HD65xx designation because of their relative performance (between the HD64xx and HD66xx dedicated solutions). The Llano processors can also run the integrated graphics in Crossfire mode with a dedicated board for improved performance, up until a certain level (aka Radeon Dual Graphics).
Intel gains graphics parity with AMD once you get to the HD67xx level (or higher) for desktops and HD68xx (or higher) for notebooks, as those models no longer run in tandem with AMD's integrated GPU. At that point, it makes a lot less sense to go for an AMD solution, since Intel has the upper hand with general processing.
It's all a matter of choosing one that fits your needs.
