Changed the submission to 2x5970 ... It's one 5970 and one 5870 , so score goes to faster GPU which is the 5970 .

As there are two cards , i selected 2x5970 . I don't think it's right to select 3x5970 , as this would move score to 4x gpu category (which is not happening here) .

2x5970 is ok.

You are doing something wrong. Now the score says 4x gpus which is not right. This result is done with 3x gpus. If I'm not that wrong 5970's cores are the same as 5870's. So why my result is listed at 4x cores?

Changed back to 3 x HD5870. You can't compare a 3 x GPU score with 4 GPUs. As 3 x HD5970 is not possible the score has to be 3 x HD5870 ranking.

Especially because Aquamark scales weird with a different amount of GPUs. In addition the HD5970 has two HD5870 GPUs which are downclocked. So two HD5870 are usually faster than one HD5970.

If you take it down to core level , yes each 5970 core is slower than one 5870 core . But overall 5970 is faster than 5870 . That's why i changed it to 5970 .
