Pros: overclocks easily, runs cool on stock cooling
Cons: a long card not for small cases
i got ahold of this reference model of the 6850 off another user here on ocn, hed ran it for about a month in crossfire with an identical card, it needs about 0.02v on the voltage to reach its max clocks in afterburner and stay completely stable, it beats the pants off the 5770 i have and runs cold and quiet on the stock cooler, the 5770 is on water because of the hair dryer the stock cooler was, ive never seen this card pass 65C full load, thrown many games including crysis at it on max settings, never saw below 65fps, usually held around 70, in most other games on max it pushes well over 90fps, id buy another one, sadly reference models arent avaliable from XFX anymore, theyve been making revision offspring cards that suck, a friend of mine ended up with one, they run louder and overclock horribly.
a great buy if you can find the reference model, stay clear of revisions.
a warning for those with anything smaller than a mid tower, this card will not fit in your case without modding.
