Both laptops have the same selectable chipsets, leading me to believe they'll be using the same mobo, and I'll be using the same processor in both.
Specs are as follows:
Intel(R) Core(TM) i5-2410M Processor (2.3 GHz, 3MB L3 Cache)Turbo Boost up to 2.9 GHz
Radeon(TM) HD 6770M w/ 1GB GDDR5 1600MHz
6GB DDR3 1333MHz
7200RPM HDD (500GB on the 17.3" and 640GB on the 15.6")
I am expecting to need a laptop for occasional classes and will every now and again bring it to the library to get work done, so the extra portability and battery life offsets the larger screen size and better resolution for the times I won't have it connected to my monitor. My most demanding application should be SC2.
