hey Ahmed

I have the GTX570 and love it. i got it because it's the most powerful nVidia card you can get for the Mac Pro without needing another power supply. I ordered it on eBay from seller MacVidCards, who flashes PC cards for Mac. If you get an expander, then you don't have to worry about power as much as they will have plenty of power for even the largest cards. I will let others chime in on the expander options, but I believe the most popular is the Cubix Desktop 4

4gb 680 is the best I believe.

would 680 run on internal power also ?

[Margus Voll] "would 680 run on internal power also ?"

I thought it wouldn't work, but I took a look at nVidia's site and it has lower power consumption than the 570.

GTX 570 - 219w - http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-570/specifications
GTX 680 - 195w - http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-680/specifications
GTX 580 - 244w - http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-580/specifications

so it looks like it will work, but you might need 6 pin to 8 pin adapters.

i may be wrong, but I believe that the change in architecture between the 5 series and 6 series has meant that the 6 are not as much of a speed bump as people were expecting for Resolve. someone want to chime in? Juan?

according to this test on Barefeats.com, the 570 and 580 hold an edge over the 680 in simple Resolve 9 tests:

The GTX680 card has a pair of 6 pin power connectors. So no adapters required. If you don't already have a pair of Aux power cables with the Mac, you would likely need to acquire those from somewhere, as they won't come with the card. So this card fits nicely inside the Mac.

I did a recent test between a GTX580 and a GTX680 in a Cubix Desktop 4 expansion chassis, using Resolve 9.0.4 and the Standard Candle 9 test, with a 5,1 MacPro running OS X 10.8.2 and the NVIDIA 304.00.05f02 GPU driver with CUDA 5.0.37, and an HD5770 GUI card in the Mac. I had "Use optimized display mode during playback" enabled.

On the 16 blur test, the 580 card had 13 FPS playback. The 680 card had 14 FPS playback.

On the 1 NR2 test, the 580 card had 13.5 FPS playback. The 680 card had 11 FPS playback.

So the 680 appears slightly better with blur and the 580 is slightly better with NR.

Based on this, it would seem like the 680 inside the Mac would have better performance than the 570 inside the Mac.

Your mileage may vary...

In my testing I've found that performance for gtx cards comes in as follows in ascending order:
GTX570
GTX680
GTX580
GTX690

I've successfully run all of them in a macpro. The 570 and 680 (not over clocked / ftw versions) work with two 6-pin power so well within the macpro power envelope. 680 FTW and 580 (not over clocked) work in the macpro but require one 6-8pin adapter. So they have 6/8pin connections. Obviously this is pushing the power envelope on the macpro. But in my now long term testing with several 580s, this has not once been an issue. The 690 (which is a beast!) requires two 8pin connectors. So two 6-8pin adapters for the macpro. I've only stress tested this for about 190 hours straight without fail, but who knows, so grain of salt. But even if you have to add additional power to be on the safe side. The thing is awesome. It's basically like having half a 3x580 Cubix inside your MacPro. And like I said, I have it working in a box using built in power, 0 power issues so far.

this is awesome Juan, thanks.

regarding power, are your computers relatively power-light otherwise? do you have spinning hard drives running in the tower or are your bays empty?

Guys, I feel like I have to chime in when it comes to overpowering cards.
It might be a coincidence, or not...but my MacPro is in Apple Care for the third time now .
I was using a Q4000 and a GTX470 together using a splitter for a good while until one day it just died.
They did not say anything in the shop...they just put in a new CPU and Logicboard.
Since then the Mac is not waking up from sleep and needs two boot cycles every time , so it went back into service twice.
I guess they will take out every part and just give me back the old enclosure with new e-parts.
Sooooo, I will stick to the Q4000 for the home system and be patient.
At work both Cubix operate as planed.
One with 4x580 PC and one with 3x680 and frankly, for any semi serious grading session, thats what you wanna do.
Leave the stress and the noise in the room next door and free your Mac :)

FYI - Cubix's 3m limit on cable length upgrades is due to PCIe spec (and physics) limitation on 16-channel signal extension via copper cabling.

When / If Cubix figures out a way to put all 16-channels of native PCIe bus signal through fiber optic, that would not only be a really cool solution to present, but also make your workstation environment much quieter. We're talking distances supported of up to hundreds of meters between Cubix device and Mac Pro.

I'd say the draw of a single 690 is less than a q4000 + 470. None of my configs use power splitters. You'll note I don't mention the gtx590 which would be outside the macpro power envelope, as would the 580 classified.

BTW using gt120s for GUI in all but Cubix config.

you use 690 + 120 or just 690?

Just to be clear.

Yep. Without the GUI card you wouldn't get full advantage of the 690.

thanks everybody for suggestions it really helped me the most
i decided to get GTX 570 from macvidCards

so i'll work with Q4000 + GTX570
with totally internal power

i think it will be great with RED footage on HD timeline
with great number of corrections
also we got SAN storage i think fiber channels will do other part of
fasts the performance

thank you all

So, wich is the best according to you: 4 giga Evga 680 or the base 2 giga model?

hey Ahmed

you can't run those 2 cards together on internal power. The 570 has two 6 pin connectors and the Q4000 has one. The Mac Pro only has two 6 pin connections on the motherboard. I would not recommend splitting the power to run these 2 cards. You will need additional power such as this:

Question: Other than the boot screen, what is the difference between using a stock GTX 570 card (I'm using the EVGA GeForce GTX 570 HD Double Shot 1280 MB GDDR5 PCB PCI-E 2.0 Graphics Card 012-P3-1577-KR) and using the one that's tweaked by MacVidCards?

I'm running 10.8.2 on a MacPro 5,1 with a GT120 as GUI

As far as I can tell, the performance should be the same from both my card and the MacVidCards one, but I've recently heard otherwise.

Thanks
Jed

To be precise then stock versions data bus runs at 2,5 gig
macvids runs 5 his.

Ok. But how does that translate into speed in resolve (faster bus does not always equal faster performance, depending on overall data flow)??

hey Jed

from what Juan has told me, when running them as GPU cards and not GUI cards, there is no difference between the PC cards and the flashed cards from Macvidcards.

Eric,
Am I wrong that the GTX570 takes up two slots in a Mac tower? I currently need two slots for RAID card and BM HD-SDI card. If I keep ATI 5770 for GUI, what would be my options for CUDA card?

yes, the 570 needs a double wide slot, as does the 5770. i had a similar issue, so i replaced the 5770 with a GT120, which is a single slot. it's a step down for sure, and i've been thinking about getting a Quadro 4000 (single slot) with a second power supply to replace it.

also, most RAID cards need an 8x slot. slots 3 and 4 on the Mac Pro are 4x, so your RAID card won't run at full speed.

It depends on your model but I believe on the mac pro 4,1 5,1 slot 3 is x8.

on my 3,1 and 4,1:

slot 1: 16x (double width)
slot 2: 16x (single width)
slot 3: 4x
slot 4: 4x

pretty sure the 5,1 is the same.

Eric,

I'm using a Caldigit RAID where all that's in the Mac tower is a PCIe card. The controller is in the RAID. I'm getting around 700mb/s Read/Write.
I've been using Symphony up til now for grading which is convenient for staying in the NLE. But I'm sure enjoying Resolve even with the ATI card.
