Win7 would choke on 1080P without hardware decode acceleration. That's not available on Windows XBMC, yet. You'd need an external player that can utilize DXVA under windows to get good 1080P playback. On linux with VDPAU which offloads decode to the GPU and makes 1080P playback possible on lower end hardware with a compatible nVidia chipse.
