really cause me and red machine have identicle rigs up to date drivers and my single 6970 wastes his 580 in DX11 games just cause a review says this or that dosent make it gospel true but fact is i have 6970 xfire and fact is i match 580 sli numbers in alot of games that are DX11. another fact i paid less to do so in the end it dosent matter that much people will buy what they buy but the cold hard fact is 6950s can now be unlocked to 6970s with a simple bios flash within windows itself and in that sense $600 6850s will slaughter a 580 at $500 price point
granted this is on AMD cpus its already been established on Intel rigs the 580 in single card mode performs better
but in Alien Vs Predator Heaven Bench etc on a 965be with 1333 cl7 ram single 6970 stock vs single 580 stock i came out on top again and again. Now if someone wants to donate me an Intel rig ill test that and watch the 580 pull ahead.
but from what i remember in legit reviews andantech 6900 cards in dual card config ran neck and neck with the 580s
my review of the 6900s i posted awhile back

If these arent enough i can grab more i mean theres alot of reviews out there i can keep grabbing bench marks but i reall dont give a shit about DX9 or DX10 performance when those games run at 200-300fps examples Unreal Engine 3 based titles and the like the fact i can now run Metro 2033 at 55fps avg 30min with all settings including Depth of Field turned on im happy if someone has 570 sli or 580 theyll get near the same performance and be just a damn happy.
Also if the forum is so AMD biased and it grinds your gears so much why not go to some other forum.
and for there record if i had the cash id buy an Intel core i7 rig right now
but fact is 580 sli might win in general by a few FPS but in no way is it worth the price 2x 6950s is $600 on newegg flash the bios you have 2x 6970s for $150 less 580 sli sits at $1000 = performance $400 less thats just a cold hard cash difference
also im gonna go out on a limb and guess the next response is that all the info ive provided in its retarded non punctuated form will be deemed biased and made up of magical fairy pixie dust made from the bones of children from Ethiopia right?
