So I ordered my MP with 10GB (2gb from Apple stock and 8gb(2gbx4dimm) from OWC. I'm loving my MP but during some intense Photoshop and Illustrator uses I see a slowdown. Obviously, in comparison, it's still fast as all hell but I'm wondering if more RAM is the answer. I went with the 2.8GHz to save cash for the RAM + 4xHDs + Eventual Quadro. Now I'm thinking maybe I should have gone 3GHz. Not a big deal, and certainly nothing I can't easily live with but while I'm still in my Amazon return period I figure now's the only chance to change my mind. Any thoughts?
