Here is the rub, I am a photographer, my Mac Pro works processing image files. I have an early 2009 octo 2.26 with 16gb of ram, and the Geforce GT 120. I need to start running Phocus (Hasselblad software) which specifically states that a Radeon HD 4870 card will speed up processing of files. I might want to get a second monitor soon, currently running a Dell 30 isp. Do I order the Radeon 4870, install it and be done with it? Or are there other (better) options out there (4890?) ? I don't want to get into a complicated installation (flashing etc).
