I read online that some had problems with your board, but the ones that didn't were happy with it. Your power supply should handle OC your CPU. Your Graphics card is already 'OC' as per your description so leave it alone. Your RAM will be fine, just keep it running within its limits (1333DDR3).
Since I am not as familiar with DDR3 or your board, I will let others supply you with more details, but your CPU should run well at 400MHz x 8= 3200MHz or 3.2GHz.
You have to be a little bit crazy to keep you from going insane.
If all else fails, read instructions.
