Can consider these from Dell:
14"
Inspiron 14R, i5-3337U + Nvidia GT730M + (1366x768;touch)@RM2099[2.33kg], 4GB, 750GB(5400rpm), Linux; W8@RM2399

[Ultrabook]Inspiron 14z, i5-3337U + AMD HD7570M + 32GB SSD + 500GB(5400rpm)@RM2549[1.87kg], 4GB, W8 *no VGA port, OD

*Use remaining money to extend warranty to 3 years on-site (~RM250) 

be noted that between these 2 models, the processor model that comes with U at the end of the model number is an ultra-low-voltage CPU. it is physically dual core while the QM is quad core. normally, the arrangement of CPU is Core i7 QM -> Core i5 -> Core i7 U -> Core i5 U

yes. it is better than i7-3517U. but according to your usage, you seems dont need the power of quad core. so you can stick to core i7 U if you want.

actually, the 'U' doesnt present at the end of a core i7 logo. i just add it to notify you according to the model number.
