Hello,

I just got an old MAC PRO 2008 with an ATI Radeon HD 2600 XT. I'm looking to upgrade the graphic card to have a better performance with 3d and video software.

Which graphic cards over 2gb would be compatible with this computer?

Apple support lists the next graphic cards, but they are all under 1.5 gb

Graphics cards for Mac Pro (Early 2008)
ATI Radeon HD 2600 XT
NVIDIA GeForce 8800 GT (part number 630-9191 or 630-9897)
NVIDIA Quadro FX 5600
ATI Radeon HD 4870, offered as an upgrade kit
Note: The Radeon HD 4870 card requires Mac OS X v10.5.7 or later.


Thanks!!
