Hi, I found a used apple 30 inch cinema hd display that im thinking of buying. The only mac i got is a mbp (early 2008 model) to run it with, will that run smooth in 2560x1600 res? I got 4gb of ram, and the 8600m gt 256mb gfx card. Im a retoucher, and a graphic designer so photoshop, illustrator and indesign will be used frequently. Any experience with this combo? thnx in advance!
