Wow, I've never heard of that being done before
Good work mate
Thanks man! Its pretty easy to do and a huge boost to this card which makes the $210 spent big value :) on each card.

yea pretty much, like I flashed my GTX570 to a 580 but didn't get the extra shaders but its still a 580.
Odd. Unless the 6850s are also 6870s that can't be 6870s... >>

no need to waste your time with it, just use afterburner and up the clocks.
can you please post a step by step tutorial so i can flash my 6850 to a 6870 btw it is a sapphire too...and if you can post the bios you flashed its way simpler:)

note though for those considering flashing their 6850 - , 6850's are either 6870's that didnt make the grade or are flashed to make the model quota. some will flash fine, others may crap themselves. backup the original bios, and have a backup video card in case the flash goes wrong.
and remember when using RBE dont have anything running in the background while it flashes. for a whole heap of bios files head over to http://www.techpowerup.com/vgabios/

So would you recommend the 6850 or spend the extra $30 and get the 6870?
Go with the 6870.

Download radeon bios editor or RBE, I had to force the bios write though, as it wouldn't do it the traditional way.
You will have to read through the RBE to understand what your doing and the risk, as you could kill your card.
I had two so no biggie, plus I love playing with tech and pushing it.
My mate has 2 6870 saphires in crossfire and he only gets 2fps more in heaven benchmark.
But his are alot hotter then my cards, lol, and use more juice too.
But if the price is right then go for the 6870, this was just a 'see you can do it' if you want to post.
I got the original idea from here http://hardforum.com...d.php?t=1562148
when I was looking at ways to improve performance.
Just had to add this, out of both the cards one of them can overclock to 950mhz on the core and the other to 930mhz on the core, both can run 1180mhz on the memory.
