I have just purchased a new laptop and I want to be as sure as I can be that Ubuntu Studio will work properly with it. New hardware (not yet delivered as of this posting):
Toshiba Satellite L870D-BT3N22
AMD Quad Core A10 4600 APU 2.3GHz (3.2GHz Turbo boost 3.0) processor
4 GB DDR3 1600
640 GB HDD

Most importantly, what I am trying to find out is whether the APU architecture will work properly with the Ubuntu Studio 12.10 in light of the lack of a stand-alone CPU and GPU. Considering the success I have had working with Ubuntu on several previous computers I assume that the OS is intuitive enough to understand the chip architecture ... but before I cause myself a headache trying to fit a square peg into a round hole I should ask:

1. Are there any known issues running Ubuntu Studio 12.10 on an AMD APU?
2. If there are known issues, is there a simple work-around (i am still a novice with Linux) or would I be better off starting with a different distro?
3. Are there any specific procedures for optimizing this distro to maximize the efficiency of my new hardware?
