As in the title need help what would perform better a HD 6950 unlocked shaders to a 6970 or crossfiring my 6850 with a 6870 or 6850? Thanks for your time and responses

Other specs AMD 925 quad core overclocked to 3.4, 16 gigs kingston hyper x ram, cooler master hyper 212 evo, gigabyte HD 6850 overclocked to 875 GPU clock 1200 mem clock, asus M5A97 EVO motherboard and a 950 watt power supply

i would recommend going with a single 6970 (more vram and less noise)
crossfiring your HD 6850 will match GTX 580 in performance, but you may face some microstuttering / lag with games that do not support crossfiring.

which country are you from ? how much do you want to spend ? selling your HD 6850 and going for a HD 7870 Tahiti LE or HD 7950 boost is the best option.

OP a HD 6850 can be sold for USD 80 - 90 . the sapphire HD 7870 XT (Tahiti LE) sells for USD 250 (235 after rebate) . comes with 2 game coupons - bioshock infinite and tombraider . if you won't play those games you can sell those coupons for 25 bucks each.

1920 X 1200

HD 6850 - 53
HD 6870 - 64
HD 7870 Tahiti LE - 100
HD 7970 - 122

at stock speeds HD 7870 Tahiti LE performs on par with HD 7950(800 Mhz) and when overclocked to 1.2 ghz matches HD 7970(925 Mhz) .

http://www.techpowerup.com/reviews/Club_3D/HD_7870_jokerCard_Tahiti_LE/31.html

the HD 7870 Tahiti LE (1.2 ghz) will double the performance of your HD 6850(875 mhz). thumb.gif

I think you got those backwards? 6850 can't be unlocked to 6970(Really, nothing can be... You can unlock the SHADERS on some older 6950's and overclock them to be equivalent to a 6970) and I kind of doubt they offered you a 6950 for $110(If they actually did, take it.)
