I am curious I wanted to run dual 6950's and unlock them to 6970, I heard you can't do that anymore, I was told to get the msi twin frozer II but they have a twin frozer III that is $60.00 cheaper. WHat is the difeerence I can not tell, Also what benifit will I get if I run two of them instead of one. People at tiger direct says there is no need for two. Or should I go and get a 6970 or 6990, what differences will I see. I have three monitors going to play Battlefeild 3 and I have 16gb ram amd fx8120 1000w gold PSU gigbyte 990fxaud3. one last question if my mother board supports thx sound what could I acheive from a secon sound card.
