BIOS MODDING AVAILABLE! Thanks to Crazynutz.
Q: What is BIOS modding?
A: BIOS modding increases your GPU's voltage from 1.175mv to 1.212mv, giving you more overclocking headroom. It increases your TDP (maximum board power) to 170% MAX, and it also increases your Fan speed from 80%MAX to 100%MAX..
Follow the elaborated GUIDE below to mod and flash your BIOS. I do not take responsibility if you mess up your GPU, but i would do my best to help "IF" anything goes wrong somewhere
Step 1: Download this Zip file
nvflash.zip 342k .zip file
and extract the "nvflash" folder to your desktop.
Step 2: Download and install GPU-Z V0.6.9, and save your ".rom" file to your desktop by clicking the the "save BIOS" button in GPU-Z.
Step 3: Run Cmd.exe (command prompt) and navigate to your Nvflash folder with this command line "cd desktop" [hit "Enter" on your keyboard]. "cd nvflash" [Hit "Enter" on your keyboard]. Then type "kgb.exe 660.rom unlock" [Hit Enter on your keyboard], and your BIOS should be unlocked. Your command prompt should look like the image below "IF" you did everything right.
Step 4: Close and re-open Cmd.exe (command prompt), and navigate to your Nvflash folder by using the command line. "cd desktop" [Hit Enter on your keyboard]. "cd Nvflash" [Hit Enter on your keyboard]. Then type "Nvflash -4 -5 -6 660.rom". At this stage, your command prompt screen should look like the image below
Step 5: To test if your card is running at 1.212mv, restart your computer, and download Nvidia Hair demo. Install and run it while running GPU-Z monitoring application in the background. If your Modding/Flash was successful and everything works fine. Your GPU should show up 1.212mv
NOTE: If you are having problems with GPU-Z and saving your BIOS, try to download your BIOS from your manufacturer's website, and take out ONLY the .ROM file, rename it to 660.rom, and move it to the nvflash folder for unlocking. Lucid Virtu Mvp software can also cause problems for you while trying to flash your BIOS. I will advice you uninstall that software as it plays no valuable/beneficial role to gaming. The latest Nvidia drivers are enough for any v-sync problems you might have in games.

You almost always pay a price premium for faster single cards. All the high-end cards are in the lower 1/2 of the chart in terms of value, and the medium-tier cards are the best value in terms of FPS/$.
Bottom-line the OP's claim that the 660ti isn't as good a bang for buck card as the 660 seems well borne out by available facts.
However, as you go up the charts, the loss of value vs. the actual performance improvement is pretty dang consistent. You lose about 10% of 'value' while gaining about 10-12% in 'performance' with each step up you make, from 660ti to 670 to 680. 'Diminishing returns', just like we (almost) always see, and likely always will.
