I actually think right now a great budget rig for the "average house computer" that games a bit maybe with a kid would be a rig with an APU and a decent SSD. They don't need the CPU or GPU power for anything really, but having it both in there for cheap + HSA and compute stuff might make random bits faster, and we all know the majority of "slow PC" stuff is due to Disk I/O which the SSD would solve.
While I am not interested in APU's for myself (although an APU + GPU crossfire setup would be awesome if it could compete in price/performance) I don't mind that they are putting work into them, and this looks like a great price/performance offering.
