As Fugitive said, nothing wrong with your PC in terms of capability.
As in your other thread and our conversation in game, try launching AH from within the Occulus lobby rather than from your desktop and see if the little freezes remain or if they go away.
Worth noting that many of us have seen freezes over the last week in the DX9 version of the game so it may be something that is out of our control and we have to put up with it. I will fire up Occulus today and see if I get freezes.
