I would like to buy a laptop which would be connected in an external monitor 27'' 1920*1080 resolution. I tend to play 20-24 tables

I am between two laptops and i would like to help me which is the best to buy


8gb ram ddr3
17.3'' monitor 1600*900 resolution
i7 2630qm 2.0ghz quad core
750gb hard drive 5400 rpm
AMD Radeon HD 6490m


8gb ram ddr3
14'' hd monitor
i5 2450 M 2.50ghz
750gb hdd 7200rpm
Gerforce GT 520m

Is it better to have a 2core 2.50ghz or an i7 2.00 ghz quad core?
Which one do you think is best to buy?
