I am planning on buying a 15 inch macbook pro but i am having trouble deciding on if i should get the baseline mbp or pay about 200 more and get the discrete graphics. I've done my research and i know that it is better for hardcore gaming and photo/video editing. I will be using my laptop for college, and using programs such as Photoshop and Dreamweaver. I also heard about Open CL apps and snow leopard. Will the extra discrete graphics card have a difference on the performance of the laptop when snow leopard comes out (i know it is hard to say before its even out). So, would it be a good idea to stick with the 9400 and save money or go with the 9600M GT with 256MB?
