G'Day I'm a graphic designer looking at getting a Mac Pro. I'll be running CS3.3 with inDesign, Illustrator, Photoshop, Dreamweaver & Flash open at all times. I was after some advice regarding the specs. Do I really need Two 2.8GHz Quad Core's to run the above fast and efficiently or would One 2.8 with extra RAM do the trick? I spoke to a techy mate of mine and he assured me one would be enough (he said Two was major overkill unless I'm doing 3D rendering etc). What do you guys think?
