OSX performance of modified ATI 4870s

[NickyD]

I've been havin gissues with my mac lately and I think it may be the video card. Instead of purchasing another ATI X1900 from Apple, I was considering getting a 4870 and modifiying it to work in my system.

The main question is have is, how well does the 4870 perform on the Mac Side? I am a photographer and edit thousands of photos at a time often opening 50 or so images in photoshop at once. Is a modified 4870 going to compromise my ability to do this?

If you buy the 4870 from apple there is nothing you need to modify.

Especially on first Gen Mac Pro, there is really no difference unless you want to run a 24 LED backlit ACD.

CS4 can't tell the difference.

Sorry, I was under the impression that the Apple 4870s don't work in the First Gen Mac Pro. Am I mistaken?

Yup they do work.

Yes you are.

I have run both the OEM Mac 4870 and the flashed versions in my First Gen Mac Pro, and I confirmed what was first reported by Barefeats...that first gens run them JUST FINE.

Well that gives me something to think about... I may be purchasing the card directly from Apple then.

Just to make sure that I am getting my terminology right, a First Gen mac pro is the MacPro1,1 with 2.66Ghz Dual-Core Xeon processors?
