I searched around and there didn't seem to be a thread discussing the graphics options on the current line of MBPs. Someone slap me and point me in the right direction if I'm wrong. I'm looking to grab a new laptop for college next semester and I want the thing to last me forever, etc., etc. Right now I'm torn between: 1. 13-inch @ $1,499 2.7GHz dual-core i7 Intel HD Graphics 3000 2. 15-inch @ $1,799 2.0GHz quad-core i7 Intel HD Graphics 3000 AMD Radeon HD 6490M with 256MB GDDR5 My question is, how much of a difference will I notice between the dual / quad core and the graphics card on the 15in? I'm leaning towards the more expensive model right now... Thanks in advance!
