And you toally ignored all the positive comments? or the hits on google?
Even in the earliest Mac Pro
The only official comment:
And most of the time, take it with grain of salt. But there is one thing about drivers, there aren't any until you get to 10.6.5, has always been a limitation.
Thanks Hatter, I don't think the official Apple comment concerns me since I primarily use my computer for photo and graphics. I also noticed that the 5770 card is no longer shipping and has been replaced by the 5870. I will try to purchase either one of these cards.
And yes, I will upgrade my system to Snow Leopard (finally) now that everyone is going to Lion. I hate messing around with my system when it's working properly. Let sleeping dogs lie.
