Yes, yesterday used driver sweeper to clean and fresh install driver.
About ram, i previously use 4850 (onboard 512MB) @ 1280x1024 @ highest setting it run smoothly, now 6870 (IGB GDDR5) @ 1920x1080 shuttering, suppose system RAM is not the cause.
I'm using Win 7, i think i no need those DX 9.0c.

I also using HD6870 from Sapphire (new HSF design)...
with reso 1920x1080, i face shuttering like you did...
using 10.10 or 10.12 giving same issue..
so I believe, this firmware still not fully support out HD6870...
though I think, overall performance 10.10 better than 10.12 especially temp rating
previously, I use HD4830 and HD5770 and both of it not face the issue...
so my conclusion is driver issue which 10.12 only transition from ATI ---> AMD ...

Question,
im using 400W CM power supply. Is it enough?
if enough, how bout OC (though i still dunno why I need to OC this card as playing games flawless)
Then,
can I use accelero twin turbo to my HD6870. Previously using it at HD4830 and OC it kaw2...
