Oh my god we have in our midst an Apple apologist in who's eyes Apple can do no wrong.
Do you understand that PCI-E 2.0 cards are backward compatible with PCI-E 1.0 and 1.1? Do you see that ATi have managed to produce a card that works in both the "old" Mac Pro and the new one? (and is therefore possible)
There is no technical reason why the 8800GT should not work in the "old" Mac pro, period!
Now I will concede that maybe this is an unforeseen glitch on Apples part and that maybe, just maybe, they are frantically looking into it trying to find a fix for us "old" Mac Pro owners. If so even that, IMHO, is a disgrace. Apple should have tested these cards on existing Mac Pros a LONG time ago. Finding out the day after launch that they don't work is just plain unacceptable and if it were M$ who had done this you'd be jumping all over them.
Please, give it a rest and think about how YOU look when deriding the Mac Pro owners who are rightly upset about this.
Please spare me your useless nonsensical attacks at me in an attempt to expose me as some sort of fanboy, to lead yourself and others to the conclusion that what I am saying is bull and should be disregarded. Check into my post history before you attempt to call me an apologist. Because I am far from it.
The fast remains that we do not know if Apple is indeed ignoring previous Mac Pro owners. There is not enough evidence to suggest such. Your haste to call me an apologist shows that your ability to reason like a rational human being is completely gone, and over a silly video card.
My attempt is in no way to defend Apple. You could not answer my questions as to whether or not Apple did this intentionally, or whether or not they have a plan. Which means you do not have enough information to come to a conclusion in this matter and immediately write Apple off. And again, this is only mere days after it having been made known that a 8800GT exists. Three days to be exact.
Now, equally spare me your attempts to make my knowledge in the matter seem incomplete. And furthermore that you have advanced knowledge. I am completely capable of reading. And I completely understand this situation. I know what PCIe is, and that again has nothing to do with this situation, as I said in the post your replied to. The problem is EFI, so why call into question something we know to not be the issue?
Now, if you know with absolute certainty that there is no reason for the card not to work. I suggest you call Apple and offer your services. As you clearly could offer them a solution with your infinite wisdom. Better yet, why don't you produce a card and resell it to the members here, since you can do it better than Apple.
If this were MS, no. I would not jump all over them without enough knowledge to do so. If it does indeed turn out that Apple said screw the old Mac Pro owners. Then yes, you have a valid claim and I would equally be upset about the situation. However, I will not jump to conclusions and make silly threats and equally silly comments without enough knowledge to back it.
You have the ability to think and act like a rational human being. I suggest you give a second though to your actions and illogical conclusions. I am a rational human being and that is what I look like. The old Mac Pro owners at this stage in the game do indeed look like babies and have no right to be upset with incomplete knowledge.
So please, spare me your childish nonsense. If you want to have a temper tantrum, go in a closet and have at it. But do not fuel hatred and anger with your grossly incomplete knowledge.
