  1. 700 should do it if you get a good brand name one.
  2. Yeah I would not recommend getting another card if you only have a 500 w power supply. I would use at least a 850w-1000w if your running two of the cards. Its better to be over your wattage instead of under obviously.
  3. Sell your 6950 add $100 and you can get 7870

    This is true, if you have a 700 w you could also sell your 6950 and get the newer series card that will work just as good as crossfired x2 6950's.

    You get 10-15% performance bump @stock but when you clock it you are looking at 7950 performance

    Seems like every new generation of cards steps up exponentially from the last generation, make a big difference.
