When true VR comes out I'll be impressed. Until then, I'll stick to my two-dimensional high definition.

I'm glad the Orange Box is on the list - years later, it's still loads of fun to play.

Yea.. that's just excessive. I can see two GPUs running side-by-side if you really have the money and the will, but any more than that is just unnecessary complication. Besides, any single one of these cards could run a DX10 game at full settings just fine.
