Hi Guys, I need a new/best card for a G5 quad 2.5. I know it's old (4 years) but it's still used quite a bit - mainly for Photoshop work. The card needs to run 2 x 23" Cinema Displays. I'm not sure if it makes any difference but it has 16GB memory (twice as much as our new 2.93 Quad can take - there's something not quite right there...) I have no idea what card to get - any help would be really appreciated. All the best!
