  1. nope there should be no bottleneck. Try installing the latest drivers (12.11). That should boost performance by a good amount.
  2. Witcher 2 is one of the few games that current gen hardware cant get great performance on, you'l have to lower some settings.
  3. Use gpuz and turn on log to file. Run it while you are playing the game then when you quit click on the sensors tab and click on the gpu load and keep clicking until you see max. Make sure it says 100%.
