Wrong. Whenever I have tried to make the argument against the "workstation" cards and saying the "consumer" cards are better, it comes down to two things.
1. The available memory on the cards. Generally the workstation cards come with a lot more memory, forcing workstation users to fork up the big bucks.
2. The drivers are much more expensive.
I have made the argument that the W9000 is worse than a 290X card in every aspect except for memory and apparently the one difference is the quality and stability of the drivers, or so I'm told. To me you are getting a 400$ card and then spend the extra 2600$ for a bit more memory and the "workstation"-class drivers.
Could it be so that Apple are writing the drivers for these cards? And in doing so the can buy the consumer chips but still get the performance characteristics of a workstation card? They do share the GPU, there is no difference in GPU. The crippling nVidia does to limit their GeForce-range is done after the GPU is produced and as far as I know, AMD doesn't even cripple their consumer range.
Wrong on many levels.
1) Video RAM is expensive but not
that expensive. Nor is software cert. is
that expensive (although nobody actually said against what the W9000 drivers and such are certified, if it is just the Windows platform, there's barely anything more than putting the code through Microsoft's funky, yet very useful, static analyser for drivers)...
2) You really think that Apple would have let some unstable a$$ drivers onto their flagship money-shaker?
3) I seriously doubt AMD would've opened its spec to Apple to allow the latter to write drivers (and potentially pave the way for fabbing their own chips).
4) W9000 and 290X are not based on the same chip - the former is Tahiti, the latter is Hawaii. Neither Nvidia's nor AMD's drivers for the latest video cards were stable/performed to full capacity from the first "batch"- it's simply impossible for them to test it against all possible scenarios.
5) Are you also saying that Mac Pro does not come with "workstation"-class video drivers?
6) Back in the day when ATI was making cards for Apple, they did not radically change the "consumer facing side" of the card designation, there's no reason for AMD to start doing so now. So I'd not kid myself that D700 is anywhere close to W9000 unless and until Apple or AMD came out and say that themselves.
Here's a thought: why don't you email Apple sales and ask them how D700 compares to W9000?

They aren't getting the driver certification that comes with the windows drivers for the firepro graphics cards. That's why the firepros are so expensive.
Certification against what? Running on a Windows box?
