I'm definitely not going to make SLI. Only once have used crossfire with 2 x 6850 - was fun, but lot's of headache sometimes =) Besides my MB can't afford that - Asus P8P67-M. Although i5 2500K @ 4.6 GHz is fair enough. I made my choise yesterday and bought AC Accelero Twin Turbo II - what can I say? Awesome (so silent). https://www.dropbox.com/s/u33aexkjlmahtwj/IMG_1993.JPG https://www.dropbox.com/s/t25094k99rjss06/IMG_1999.JPG https://www.dropbox.com/s/7y9wv5bvi5f33eq/Twin%20turbo%2012v.png

MSI AB works just fine, the same way as Nvidia Inspector. Besides EVGA Precision X isn't even near to MSI AB in terms of user-friendly interface IMO. And I've already made everything I wanted about clock profiles. 1189 MHz\6800 MHz is almos the same in games as 1202-1215 MHz\ 6000 MHz but better in terms of temperatures & noise. The only thing left - to decide about leaving stock cooler or buying something like AC Accelero Xtreme III or Hybrid Cooler (not cheap solutions, but even now in my country there aren't any non reference GTX 780 cards available).

svl7 thank you vm for mod bios! Flashed it on my gigabyte gtx 780 reference without any warnings with kepler bios tweaker and nvflash. Stable clocks are very nice, 1150 MHz for GPU without voltage adjusting is great, but there is an issue with Memory OC - on stock bios it was like 6800-6900 MHz stablea OC , now only 6300 MHz, with higher clocks - driver recovery (320.49 beta, win 7 64bit sp1, MSI Afterburner)... Any advice? Thanks! P.S. Problem solved... 1150 MHz on GPU without adjusting voltage is stable only when the memory isn't overclocked. 1125\6800 MHz stable so far in Valley benchmark. But there is another issue - adjusting voltage gives nothing. Any value - +37, +50 and even +100 mV - in monitoring max value is default 1.175 V. The same picture is also with nvidia inspector. On stock BIOS this card was working fine 1176\6800 MHz or 1215\6000 MHz +37mV. Now it can't handle 1150 MHz - strange =\ P.P.S. Modified myself stock bios, there is boost but at least voltage regulation works fine up to 1.2 v (1.212v gives only +13 MHz more), so now it's like that http://img.techpowerup.org/130710/nvidia_20130710_125651.png Power limit set max to 110%. This way I get 1124 MHz\6800 MHz (1.162 V) and 1189\6800 MHz (1.187 V). 1202\6800 MHz works fine with 1.212 V (need to force in P00 state constant voltage - 1.212 V) but I don't want 3-4 degrees more and noise in exchange for additional 13 MHz on GPU. So using bios with default voltages (1.2 V max, but monitoring shows mostly 1.187 V). Kepler BIOS Tweaker v1.25 works great without issues for editing bios. Then just command line, cmd and nvflash =)
