Today we will be taking a look at the new HIS and Sapphire 5970's and as they sent us two of the cards apiece we felt it would be a good time to to cover Crossfire X configurations - for those of you rich enough to be able to afford two of these monster graphics cards. We also overclock our watercooled Core i7 processor to 4.1 ghz and the memory to 1800mhz to mirror a real life environment for a potential customer of two of these high end boards - we want CPU limiting at a minimum.
