Need help deciding between two laptops.

So I am trying to decide between the sony vaio s series 13 inch SVS131290X which is $879 (when customized with better screen and gpu) and the lenovo Y400 95232FUb which is $849. Basing these prices off their own websites.

Sony pros:
1600x900 display

cons:
no ssd
1 gig gt640m le vs. the lenovo's 2 gig gt650m

Lenovo pros:
2 gig 650m
1 tb hdd and 16 gig ssd

cons:
1366x768 display

I'm a student looking for probability and gaming, which is why I opted out of anything bigger than 14" (ie the y580)

Anyone have any idea which is the better laptop?
