Here it is link to HD 3870 review and Crossfire X. Well, it's only in 3dmark and o/c, but soon there should be more tests. Look at words about heat and noise, 2slot cooler is quiet and card is cool (3870 40*C+! and 3850 30*C+) - it seems tahat both cards have great O/C potential, I wish ...

And another review: http://forums.vr-zone.com/showthread.php?t=203346
Look at image quality in Crysis OMFG, but well there is 'too low FPS' for these cards don't you think ?

We're waiting for more reviews. But rly in my opinion at price 219E in Austria HD 3870 is awesome card. And Crossfire X ... HD 3870 and cheper 3850 working together mhmm !
