graphic card upgrade MacPro 1,1

I'M not sure about GT660, though HD7950 Mac and PC edition is available.

Not sure it works on Mac Pro1,1

I personally recommend you HD5770, since it's reasonable price and perfomance for your Mac Pro.

I have a 1.1 and replaced the old card with a Radeon HD5770, and it works great. If you go this route, buy it from Apple.... if you get it from a bi-box store, it may be flashed for PC, not Mac.

An ATI 5770 is the fastest your 1,1 can use due to hardware limitations of having PCI-e 1.0 slots.

The 5870 or faster and any GTX series will be a waste since they cannot be used to anywhere near their capacity.

The GTX660 requires 10.8.3 to operate. All you will get is a blank screen.

I researched this about a year ago for my 2006 1,1

GeForce 8800 GT was the only option.

Some, most cards, are for 2008 3, 1 EFI64 and not MacPro 1, 1 so don't listen to this dealer.

Hatter, they will work in a 1,1 with 10.7.5 but as noted above, their performance will be significantly limited by the PCI-E 1.0 slot.

Hi ,

In mac pro 1.1 the ATI 6870 (PC) work with 10.7.5 (tested, just you loose the bootscreen) but the new 7950 mac edition run (always on 10.7.5) in appareance. So, the Mac rumor's members reports the driver's are not functional for 1.1.

I have the 6870 Sapphire PC and she work perfectly. Just need two 6 pin connectors. I can play COD, The Witcher 2, Skyrim etc etc. Anothers cards works. GTX 460, GTX 560ti GTX 570. You need download the Nvidia drivers in their website. If you are on 10.6, only the 5870 mac edition works.

Hope my english is correct (i'm french lol)

Hey,

Most probably this outdated, but there is some good news for owners of older mac pro models:

"Since OS X 10.7.5, Mac Pros will work with plain vanilla PC cards that have Nvidia graphics processors on them. Apple's standard graphics drivers now support them."

You may want to visit the link, since there is some other useful information found there.

Hope this helps!

thanks for the great news!
may be a dumb question but what are vanilla pc cards? 😀

ok never mind I got it, and yea it was a dumb question 😀

So really ANY nvidia graphic card would work on the mac pro?

no worries about the 'vanilla Card' - I googled it too, and very probably felt exactly the same when I found out 🙂

I did not actually try every 3rd party card in my mac pro myself, but since the drivers are present (included from OSX 10.7.5 onwards) and the hardware is compatible - it should work.

There will be on drawback on non mac-certified cards:

You will have a black screen until the login window appears. In addition to looking spooky this circumstance can be a bit of a hassle when it comes to switching between different operating systems [still possible, but you have to know the according keystrokes by heart]

Also you will have to draw the ventilation power from one of the optical drivebays, since most of PC cards have different power connectors onboard - for stability reasons I would leave this optical bay empty.

For the first few hours I would keep an eye on the temperatures of the graphic card, if it gets too hot: a stronger fan will set you back about 15 $, that pays off.

There are some reports from People out there stating it works, with different (non-mac) nvidia cards.

Before buying a specific model I would look for some reviews (obvious, but you never know..).

One important thing ro consider is you mac pro model: The Bottleneck problem.

There is no use in putting an expensive high performance card into your mac if your bus can't deliver the data

in time.

Assuming your mac is a bit older, you might find some useful information on different working configurations and benchmarks. This site is from 9/2012 but has some additional benchmark information and could come in handy if one has to choose an appropriate card:

Hope this helps

I have a MSI GTX260 PC card, So in theory this should work? Ill have to try it.

Tried it. Didn't work. On to the next one.

As I posted above, I did a bit of research and for the rev 1,1 Mac Pro, GeForce 8800 GT is the only upgrade option. And I have one in mine so I know it works.
