So i just recently upgraded to 3x 144hz 3D (VG248QE) monitors and decided to put my old 660 Ti to good use as a dedicated PhysX card. Im having a problem keeping the 970 FTWs in SLI, and 3D capable. I've tried setting them up in 144hz/60hz, with and without sli & surround and then installing the 660, but SLI is an option once installed, with any setup.
These are what Ive read through so far:

Update:

In the interest of time, I just called EVGA support on behalf of your issue. There is an issue, but it's not the one that I thought it was. The incompatibility has nothing to do with your model of blower. They have informed me that SLI configurations are not compatible with Fermi and Kepler as PhysX cards, which your 660 Ti is a member. There is no work-around. They also mentioned that you'd see a negligible improvement even if it did work.

I recommend that you sell the card used on Ebay and buy yourself an upgrade with the money.

What are the precise model numbers of you EVGA FTW cards? 04G-P4-2978-KR OR 04G-P4-3978-KR?

Does SLI with the GTX 970's work if you remove the GTX 660 Ti?

Sorry for this question, but you're not trying to place the 660 Ti into SLI, right?

What is the manufacturer and model # of your power supply?

The FTWs are 04G-P4-2978-KR, and the PSU is an EVGA 850 G2+. They work as they should without the 660ti installed, but with it installed, SLI is not an option, nor is Stereoscopic 3D.
