I just want to make sure before I do it. As now I can not use multiple GPU (2 HD 5970s) to do calculation, someone told me that if I use older version driver ( say version 10.1) then I can do it. Another way is to do it in Linux system( It seems that I can not find the second HD5970 when crossfire is disabled in windows 7). Do they worth a try?
Thanks a lot.
