Wow, that's awesome! Do you really think that it would display graphics like this though?

On the crucial assumption that someone ports or makes games that have graphics of that level, it certainly ought to. That particular image is from Heretic II, which there isn't source available for, so unless there is an open source interpretter for the data files, it probably won't display that particular image at any time (except trivially by an image viewer, of course).
But that said, Heretic II is a Quake 2-based game. And as far as we know, even Quake III isn't going to tax this baby. It has potential for some incredibly cool games to end up on it
. Look around the various forums and find out what people are planning to port as and when, and that'll give you an idea of what to expect
. Particularly the "list of actual planned projects" in the Dev forum.
