Hi, nice thorough review, as always. Looking through the review though and O/C performance seems really weak, considering the nice O/C you guys achieved. Only ~10% improvement, in AvP over the reference 7850 even though you have attained ~40% O/C over the reference model. Still being slower than the reference 7870 while running at 20% higher clocks also doesn't add up. SI scales much better than that. Do you have any explanation? Thanks
agree it using HD6870 in my PC and a HD6850 in another PC... the overclock HD6850 hardly reaching the same performance with the HD6870
