Hi there i owned a Mac Pro for about 1 month now and I'm about to buy the ATI Radeon HD 4870 fromt he Apple store for it =) Since I'm new to this i have a quick question. Once i have installed the graphic card on the Mac will the drivers for it be installed by the operating system or will i have to install them on my own? I tried to look on ATI website but couldn't find any link to drivers for the 4870 for the Mac OSx. I don't use boot camp only run Mac OSx will mainly use this card to get better performance in WoW. Thanks in advanced.
