I am sure that you must be knowing, that with the Radeon HD 6800-series AMD 2010, a new "Performance Series" presented at the end, which for the time being of the Radeon HD 6870 and Radeon HD 6850 was composed. While there have been of the latter from the very first day on the number of original design manufacturers, had to manage the larger version a long time exclusively to the not exactly ideal reference design. Actually I want to try the 2x Radeon HD 6870, but never tried of it. I am sure that performance will increase, still want to know about it. Please provide some information about the performance of 2x Radeon HD 6870. More detailed notes would be helpful.
