anybody used the new GTX 750 Ti with OS X (MacPro)?

Just curious about those cards.
Their power consumption seems to be very decent.

Not on a Mac Pro but on may PC I am pulling 50 to 55 watts under full load.

That is really a fantastic low watt usage. Do you use one or two cards?

And what do you think about the GPU Cycles speed compared to other cards?

I can not speak to other cards because this is the first CUDA card I have ever used and I have only had if for a couple weeks. I am considering a second card but for now my current project renders in 1h 59min @ 2400 samples on a single GPU.

Ah I see. My GTX 570 is great specifically during the winter as it functions as a heater
and during the summer this is not so good.

So the low watt usage is really attractive. I am just curious about computation power.
but boy the cards are cheap

Running between 60% - 75% of the available power on the PCIx slot (75w I believe) while maintaining 92% to 99% GPU load.
