Hey all, I'm about to get a new laptop and need to choose between the Core i7-3520M (2.9GHz, Dual Core) or the Core i7-3720QM (2.6GHz, Quad Core). Which one should I get and why? Pricing is not a concern as they are only $40 different. I am want performance, but wonder if the Quad Core 3720QM will be hotter and consume battery life quicker than the Dual Core 3520M. The laptop will be running Windows 8, 4GB RAM, Intel 320 SSD. I will be using it for MS Office, some graphics apps like Photoshop, and other light-office work. Thanks!
