When you say 'beefier gpu' what kinda performance card are we talking about.
Would a NVidia 7600 do, or the new Intel GMA X3000. Some new intel boards
are gonna be coming out with integrated hdmi out (powered by an intel gpu,
acclaiming DirectX 10 compatability (not that I care about that, just the
performance)). Don't know whether it is just a modified X3000, or actually a
new chip altogether. It's the 'bearlake' chipset (review of one of the non
hdmi boards here:
http://www.engadget.com/2007/05/22/intels-p35-bearlake-chipset-gets-benchmarked-reviewed/
).

Hopefully the boards will have good linux support, including the graphics,
which means that 1080i over 1080i DVI/HDMI will actually be possible, and if
the gpu is powerful enough full opengl playback may be possible.
