I think the per eye resolution is 960x1080, so overall it has an “ordinary” 1920x1080 resolution. But since the scene has basically to be rendered twice, optimization and planning is really important, just as you said. However, the question is what graphics card you can expect in a typical Oculus owner’s machine once it’s going commercial. Maybe it is a GTX 770 or higher because the launch is some time away, or because a typical Oculus user is a hardcore gamer anyway. Maybe not. This might become an important issue in the adoption of the Oculus itself and of the games we build for it.
