I can confirm the mod done by blanka.

But I pimped it a little bit.
670GTX to K5000 works!
R4 on the front side.
R1, R2, R3 on the bottom side.
K5000 works absolutely stable for me, but has no performance increase in SPECviewperf. I tested with few different Quadro drivers.
Summary
GPU Name R1 / 0-7 4th byte R2 / 8-f 4th byte R3/ 3th (high) R4 / 3th (low)
GTX 660Ti 20K None None 25k
GTX 670 None 10K None 25k
tesla k10 none 40K None 25k
Quadro k5000 none 15k 40K none
grid k2 none 40K 40K none
I flashed it (EVGA 670GTX 2GB 915MHz) with the K5000 bios from techpowerup.
"nvflash.exe -4 -5 -6 K5000.rom" had to be used because of different subsystem and board id.
It started with minor pixel errors but booted into win7.
After driver installation and reboot win7 didn't start anymore.
Flashing it back worked without problems.
Hi,
I did some research on my own about the GTX670/660ti vendor layouts because I wanted to have a cheap Grid K2 from ebay.
I want to share with you the things I found out the last two days.
Please be aware that this is only theoretical stuff, so I never tried it out by my own and it's on your own risk if you try it out!If you want to try it, it would be kind if you reply if it works.
Now the explanation:
1. By comparing the various GTX670/660TI layouts I found out that the Gigabyte 660TI layout seems to be exactly the same layout like the normal original NVIDIA GTX670 layout.
2. I found a high resolution picture of the Gigabyte 660TI back- and frontside and seperated the important views of capacitor 1 to 4 (picture 1).
3. By random I saw that fortunately the capacitors have names beneath them (e.g. R137).
4. I seperated the capacitor names as you can see on the right side in picture 1.
5. I also compared the layouts of various vendors and found other vendors with the same layout like the Gigabyte 660TI. I wrote the models ontop each different layout. Please reply whether I made a failure.
6. By searching throught the various vendor layouts I recognized that the Asus 660TI Cards and also the MSI 660Ti Cards have named capacitors.
7. The Asus 660TI has the same layout like the Asus 670. By writing up the names of the capacitors again I found the probably right capacitors you have to modify (have a look at picture 2 and 3).
Here some overview:

I also uploaded a gif to compare the various cards more easy:
