So here's my question. I'm trying to decide if I should go for the MacBook Pro 15.4 inch with 128MB or 256MB ATI Mobility Radeon X1600? Yeah I'll get 0.16GHz faster, 512 MB RAM, 20 GB hard drive space, and 128MB more graphics, but for a difference of $500 is it really worth it? My main uses will be Photoshop & Illustrator graphic design/illustration work plus also use it as a digital sketchbook/paintings (Painter 8). Not so much into games. Don't think I'll be doing Final Cut Pro or complex editing on it either (but highly likely will get FCP in a year or 2). I also plan on using an external monitor too. It'll really help me out if this Mac community will give me some advice. My budget is very tight. Got like $2000 to spend plus I'll get the educational discount too. Thanks!
