When you guys run the 580 do you have an extra psu? Doesn't it need an 8 pin as well as a 6 pin for power?
Got a tip for us?

The safe and recommended thing to do is add an extra PSU that has sufficient power and the right connectors (8-pin, 6-pin, etc. as required by your chosen card). You might prefer to fit something in the second 5.25" bay (like this: http://www.newegg.com/Product/Product.aspx?Item=N82E16817104054) but that will add a lot of heat inside your case.
So you could stick it outside the case instead...and use a bigger PSU if you need the power.
Just tried it on my Mac Pro 1,1 using an EVGA GTX 570 without helper card. I noticed you don't really need kextdrop or kexthelper, I was able to open webDriverPayload_SVSSJ.pkg and installing it with no issues. No need to go inside and drop the kexts manually.
I did the ATY_init and kext fixes initially, but after realizing I could install this, I deleted ATY_init and installed.
Thanks for all the info
(I attached a screenshot of Sys Profiler and one of the installer.)

I personally have a 580 which needs 2 8pins to power itself : the Asus 580 DirectCu II.
As the Mac Pro only has 2 6pins connectors, and as I really don't want to make it burn, I bought a classic PSU to feed the 580
But I wanted a silent one, so I bought the Seasonic x-460FL : a 460W fanless 80+ gold PSU giving 2 8pins connectors (and more).
It is a bit expensive (~150$), but I wanted the most silent one.
I used the power of a sata connector and a relay to power on and off the second PSU with the Mac Pro's PSU.
So far everything works really great !

could you try some game to test it ?
Its more of work machine (maya, 3ds max, fume etc). But I did install skyrim and played without any problems with all settings maxed out.
hope that helps.
THat is just how it is. ATI/AMD makes cards that run multiple displays, Nvidia makes cards that are "smarter" (i.e., run CUDA) but can only run 2 displays at once. They have an oddball card or two in PC world that sorta runs 3 displays but it does this by drawing a 3840x1080 desktop across two. The cards and the drivers are 2 display only.
This is especially true in Mac world. Have a look at pix of Quadro 4000 for Mac and PC. The PC one has 3 ports from which you can drive 2 different images. The Mac one has just 2 ports. OSX has an even harder time dealing with the 2 port out thing, can't even pick from three. (Look at Quadro 4800 too, same thing)
BTW, I think this is why we see fewer Mac Nvidi a cards. As the drivers are, it is easiest to have 2 display cards run in OSX. To create the Mac Quadro 4000 they had to draw a new PCB and manufacture it separately and package it and sell it all separately.
We can make Quadro 5000 and 6000 run great, we just have to "kill" one of the ports. It is likely that nobody wanted to bother setting up a whole special PCB and factory run for some $2000-3000 cards that few would buy. If all it was a a different ROM, we would have them.
Hi Guys, some advice..
Would the GTX570 be a decent improvement over the GTX285? I don't have the cash to blow on a 580 & power supply (that would be about 600 here) especially with the iPad 3 due, but i could stretch to a 570. Also a 570 wouldn't require an external power supply id that correct?

gtx 570 requires 2 PCIe 6 pin cables for power. And they are not included, but can be found online for under $10 each.
I think it's worth mentioning that this support can be removed in a future OS update. 400 series got support to init themselves in 10.7.0 and then it disappeared in 10.7.2 only to reappear in 10.7.3.
So this is actually a much less future proof idea then flashing. (Although we can't flash 580 yet.)
Not to mention you can't boot Lion install disks/USB's anymore if you get this card.
Just an FYI before you go out and buy a $400 card.

I did the clean install from a USB entry, is there anyway to inject the update into the install? I use to do it with my windows installs, surely there's a way?
Doubtful. The 590 is a dual GPU card that runs using SLI. If it worked, best possible performance you could get would only be using one of the GPUs, which would make it the same speed as the 580.
Don't see why not.
Looking at price of a 570 which was still 350 here ($450) or the 580 around 500 ($650) and considering Cindori's wise words that whilst this may work now, there is no knowing that it if it could be taken away / broken in the next os update I decided to play it safe and buy an official Apple ATI 5870 HD I found from a seller in Apple reseller in cork for 260, and they offered me 100 trade in for my GTX285 reducing cost further.
Whilst I'm sure it won't give as big a performance leap as the 570,580 - it's the safest bet for me at the moment. I had issues with flashed 4870 cards previously, so just want something that works.
