All in all a 6850 is a better buy, uses less power, only needs 1x six pin. Runs cooler, overclocks more. 6850 to 6870 see's little to no difference in most games. It's also cheaper..
And not to forget when overclocked (if you get a decent one) a 6850 blows a 6870 away in the benchies.
Plus 6850 is easier to run in Crossfire, less heat, cheaper, less power connectors. More overclocking!
^Not word for word but a statement like this is what caused me to buy it in the first place. Plus it was on sale at around $150 which was the same as the HD5770 at the time of purchase.

Don't know if it's been answered somewhere in 500 pages, but i am going to ask anyway. My 6850 starts producing artifacts and eventualy crashes when temps rise above 73-74 Celsius running furmark stress test. Is that normal ?
EXACTLY what I was seeing too. The card is ok physically over those temps but emotionally they don't like it. lol Everytime over 65 it was artifacting a little bit. Over 75 it would crash. No problems when at stock and over those temps. But when overclocked, it has it problems.
I have found after putting a watercooler on mine and at the same clocks but lower temps, no artifacts or crashes.
