SLI GTX 970 a possibility?

[theitsage]

I found a GTX 970 at my local Micro Center and decided to give it a shot. Swapped my R9 280X out for the GTX 970 which has the same 6pin and 8pin power plugs. It works with the latest web driver as expected from the reports in the other GTX 970/980 thread.

What got me intrigued was the TDP rating of 145W on this GTX 970 GPU. I went ahead and use an adapter to draw power from Booster A connector to 6pin and 8pin power plugs. It works the same way and sees no drop in performance.

I don't have neither a free PCIe slot nor a second GTX 970 at the moment. My hunch is that a SLI GTX 970 setup with only internal power supply is possible. Anyone tried it yet?

Can you imagine the performance boost?

Does OSX or the oMP chipset support SLi? Beside SLi isn't required for Cuda as it support multiple GPU without the SLi bridge.

OS X doesn't support Crossfire/SLI. I'm mainly interested in SLI for gaming in Windows.

It's nice to know that one can install 2 of these GTX 970 GPUs in a cMP without needing an external power supply...be it for video work in OS X or gaming in Windows.
