6970 (925mhz) in 2,1 mac pro

[gab1982]

Hi I have a MAC PRO 2007 2,1 edition, here are the specs:

Model Name: Mac Pro
Model Identifier: MacPro2,1
Processor Name: Quad-Core Intel Xeon
Processor Speed: 3 GHz
Number Of Processors: 2
Total Number Of Cores: 8
L2 Cache (per processor): 8 MB
Memory: 5 GB
Bus Speed: 1.33 GHz
Boot ROM Version: MP21.007F.B06

I currently have 3x NVIDIA GeForce 7300 GT in place and plan to keep 1 but sell 2 of the others.

I play a lot of gaming via windows in bootcamp and want a new card:

http://www.scan.co.uk/products/2gb-...gddr5-gpu-925mhz-1536cores-2x-dvi-2x-mdp-hdmi

Will it work in windows?
Will it work in OSX if flashed or whatever needs to be done?

I want the card for gaming and I want to in the future use it to watch blu-ray 3d movies, play 3d games etc.

My motherboard has 2 6 pin power plug holes and i see from the card it has 1 6 pin and 1 8 pin, i have seen a few convertor 6pin-8pin cables on ebay and if so would they work?

thanks
Graham

It will work BUT you need to cut the power to it when booting into OSX or the computer wont boot. As yet (as far as I know) you can't flash it to run in OSX yet.

Power cable converters should be fine.

It won't work under OS X at all. Perhaps in the future, but not now.

You don't need adapters. Just plug in two 6-pin cables and you'll be fine. I ran that way for months upon months with my own card.

But do you need to cut power to the card when booting in OS X ?

I think you might be assuming I had a 6970, so let me be more clear about that – I had an ATI 4890. With a 6970, you could leave it plugged in (assuming you had a card that OS X would recognize also in the system), but you'd have to unplug the cable from the monitor and plug it into the other GPU every time you switched OSes, and under OS X the fan would run at full speed, IIRC. It isn't really a good solution.

Were I in your position I'd go with a 5870.
