The GT680 is going to be an amazing card for the MP. Performance is nuts and the high end card falls within the power envelope such that it won't require an external power supply.
Looking at netkas forum posts, it looks like the 680 is a no go in Lion and Mountain Lion preview for the moment.
So these cards are great for CUDA, but what about OpenCL ? Does the extra power benefit apps using OpenCL (which supports some Nvidia cards like the GTX 285), or is it limited to CUDA ?
They alright in OpenCL. AMD dominates in OpenCL.

Not correct in OSX.
Apple, being bad sports, don't have OpenCl turned on for Fermi cards. They flip a couple bytes to turn it off and help keep the 5870 looking good. If you can't win a fair race, CHEAT !!!
A question, for anybody...
I don't need hardcore graphics in OS X, I use an "official" 5770 for my MP and it works fine. But I do game, on a "PC", and could do with less computers.
Is the GTX 570 a good option for dual-boot gaming in Windows? Does it still need modding for full performance?
Apple doesn't have to cheat. It is the same results in Windows as I posted.
Test were in Windows 7 SP1 (no supposed favoritism to AMD). So Windows cheats too then? How do you figure Apple cheats when both Win 7 and OS X show AMD destroying Nvidia by default? They all want to beat up on lil' green? Cool that Apple "fixed" their drivers but what about Windows gap? It is still there no? Wouldn't the apparent gap in both mean that that is the normal not the cheat? The 5870 is old as hell. I don't expect it to win much these days but the disparity shows something wrong with Nvidia. I wouldn't think Apple cares enough about any of this to alter results to favor their old-ass tech but you are closer to these things.
The OpenCl for ALL Fermi cards is TURNED OFF by default.
There must be some reason they came up with PCIE 2. In the next Mac Pro, quite likely we will have PCIE 3. If you are fine with PCIE 1, just get a PC 570 and be done with it. Nobody is forcing you to use the newer standard. Lots of people are just fine at PCIE 1.0.
Our "slowed down" 480 does 1100 Gflops in Single Precision CUDA. An EVGA 570 Superclocked does 1500 on the same power. Technology is amazing.....
He posts about GTX 570 and GTX 580 with EFI boot screen.
Just for his business.
Never post how that was done (how to write EFI part).
My thought exactly! There is nothing wrong to make a few bucks, but this is not the right forum.
MacVidCards,
So now the 10.7.4 update has come to Software Update. However, I installed the update and now, the Nvidia drivers no longer work anymore with the GTX 570 I just bought from MacVidCards. The acceleration is gone (used to work swell under 10.7.3)
Any clues?

This appears to be the driver for 10.7.4 for what it's worth.
Will a Mac Pro 5,1 be able to run 4 displays using a MacVidCards configured GTX570 + GT120? I understand that the 570 will run fine with boot screen in 10.7.3....has anyone tried to add a GT120 to add two more displays?
I'm guessing it should work since the 120 does not require power.
