I would love to try that but I am running on linux (ubuntu) and so can't easily overclock as far as I know.

Unless people know otherwise?

2 x 750 (non ti) give me 4.1-4.2 on X11. Overclocked (see my other post).

planning to replace my 40 280x with 66 Ti's , will save 1/2 of power costs.

With the lastest driver, it's possible

I have share the info in this thread : https://bitcointalk.org/index.php?topic=167229.msg7718377#msg7718377
YOu can also asking info on the KopiemTu (Linux nvidia mining distro) (link in the previous message)

The overclocking settings changed in new drivers for linux.
you set offsets from default clocks now, instead of absolute values
This worked for me

export DISPLAY=:0

/usr/bin/nvidia-settings -c :0 \
-a [gpu:0]/GPUGraphicsClockOffset[1]=80 -a [gpu:0]/GPUMemoryTransferRateOffset[1]=950 \
-a [gpu:1]/GPUGraphicsClockOffset[1]=60 -a [gpu:1]/GPUMemoryTransferRateOffset[1]=950

/usr/bin/nvidia-settings -c :0 \
-a [gpu:0]/GPUGraphicsClockOffset[1]=92 -a [gpu:0]/GPUMemoryTransferRateOffset[1]=966 \
-a [gpu:1]/GPUGraphicsClockOffset[1]=66 -a [gpu:1]/GPUMemoryTransferRateOffset[1]=966
