    That's what I was told both crossfire it with my 5870 XXXEd
    And that indeed it is 2 under clocked 5870's
    No advice on cooler sorry
    IMO it is a fairly good cooler on reference cards, but I
    say that because of the HAF case
    Morgoth says thanks.

    I'm still unclear about tesselation if it
    is a big increase or do you need to move
    to 6970( from 5870) ???

    Tessellation alone is not worth going to a 6970 from a 5870. The 5870 is still a great GPU, and tessellation aside the 6970 won't give you a significant enough boost in overall performance to justify the cost. You are best to wait until 7k series cards are out at the least.
