New video card driver issues

I just got a new video card and updated the driver to the most recent one. Now blender go fast :yes: But for some reason i’m having some issues. First, planes act as if their normals are flipped, i.e. i can only select them from behind, except for in Solid or Wireframe mode, but i can still see them from the front. Second, sometimes objects will get these little squares or rectangles around them that are the same color as the background. Third, sometimes textures will act as if they are on reflection mode in realtime texture mapping when the camera gets near them.
Video card is a Radeon 9500
