Well, I said, what the heck and went ahead and bought a Gigabyte GTX780 Windforce3 OverClock GPU. This one:

The GTX700 series has a new feature, the Base/Boost clock rate is determined by the temp of the card. When the card gets hot, it clocks itself down. The OC model that I have has a base clock of 954 MHz and a Boost clock of 1006 MHz. This bests the standard GTX780 that has clocks of 863/900 respectively.
The cooler is, IMHO, a work of art, containing copper heat pipes, and the design, IMHO, is the best of the current breed of graphics cards:

My card was modified by the impresario of Mac Graphic Cards - MacVidCards. This is the second card he has done for me. Both were 3 fan Gigabyte models. The Boot Screen shows up, as it should, just like a real authorized Macintosh Card, except it's much faster than anything Macintosh offers. The Mac community is indeed lucky to have the talents of this guy, and Netkas, available to us.
I thought he would turn the clock down for the Mac, but Cuda-Z reports I'm running at a core clock rate of 1006 MHz and my 3GBs of memory is running @ 6008 MHz.
I'm happy I spent the money on this baby, but Open CL is not yet supported in 10.8.5. I Believe it is in OS 10.9. Maybe the next release of the Web Driver by Nvidia will contain the necessary software to enable Open CL. The GTX780 made a decent showing in Bear Feats tests in Open CL, but they were running Mavericks (10.9)
With this card mounted in slot 1, the base under the card acts like a thermal plate, it heats up when the card is under load and cools down when the card is at idle.
I'm attaching a couple of screen shots that shows the results of Heaven and Valley.
