For me the exciting thing about the HD prototype is that (correct me if I'm wrong here) but it had separate 1080p screens for each eye.
Not only is that awesome resolution, but by being separate doesn't that mean that you can use separate graphics cards for each eye?
Hence a pair of GTX 780s would mean everything would be butter smooth at top detail.
One of the problems with the Rift is that SLI/Crossfire introduces too much latency so you need one giant card to do everything. Therefore to get a good resolution AND a good frame rate you need something HUGE.
