Just needed some help with my decision making. I have a Mac Pro 1.1 2 x Dual Core Intel Xeon 2.26GHz only 4gb Ram and I would like to give it a bit of an upgrade I mainly use Photoshop, Illustrator etc and I would like to do some gaming aswell so I want to drop in a 4870 gpu. Is this Possible? If it does not what should I do in order for it to work ie upgrade processors and add more ram. Tried searching for a similar thread but couldnt find any answers. Thanks in advance guys!
