I'm most likely going to get a 15" with the i5 or i7. I plan on running CS5, and lightroom with this. I do concert and wedding photography so I'm going to be going through and editing lots of pictures. Not currently but within a year or two I will be doing light video editing(shot from SLR). Do I go with the i5 or i7 and do I bump it up to 8gb of ram or will 4 be enough? I def. going to be getting: 500gb 7200 HD as I cannot afford SSD. 15-inch Hi-Res Antiglare Widescreen Display Mini DisplayPort to VGA Adapter(to plug into my 22" monitor) Any light shed would be much appreciated!
