I am planing on getting another 6870 in May so I can crossfire. Will there be a price drop in the 6000 series because the 7000 series is coming out early next year? I am asking this question now because I am still a little worried that they will discontinue making the 6870 so by the time I get out of school and get a job and get enough money, I will not be able to purchase the 6870 anymore. Thanks
