I know story about Nvidia GPUs. I used Linux for a long time. In Linux Nvidia GPU is disabled and this is great for me. I need Nvidia (or AMD) GPU only in Windows. On Linux Intel GPU is sufficient for me. Nvidia's GPU is powered down by default. Unfortunately OpenBSD doesn't know how to turn off Nvidia GPU and as one of developers told me on ports mailing list, there is no driver easy to port to OpenBSD to turn off that graphics card.

I read this before, but thanks. Newest AMD's APUs are based on GCN (like ATI Radeon HD7770) but only newest. Older AMD's GPUs in APU are based on VLIW-* architecture and in Linux are well supported by open source drivers. So I am considering purchase of laptop with APU based on that architecture. I think performance in Windows will be sufficient for my projects, and only bothers me temperature (and compatibility) when I will run OpenBSD on it.
I searched mailing lists but there a little recent informations about AMD GPU and none informations about APU's GPU (integrated with CPU GPUs).
