Is HP 15-ab214TX laptop a good buy with i7(6th gen) but only dual core

I see a good deal for HP 15-ab214TX laptop with i7 processor (6th Gen) , 1TB hdd online. From number of days, I want to upgrade my laptop because my current laptop Asus K53S is old and sometimes I feel that it not fit for latest applications and even for my casual gaming. ( I can play old games very well on it but no latest one are playable). So what I want is to go for a i7 based powerful laptop but not very costly like 80K or 100K, but something about Rs. 50K -60K.

My basic requirements :

1. Fast,
2. Can play latest games atleast at medium settings
3. Good battery backup
4. Not very heavy
5. Whichever brand, should have good network of service center.

My choice is HP 15-ab214TX which is available via ebay for Rs. 58K while all others are selling it for more than 72K . I asked seller he confirms that there is valid India HP warranty. So with this sweet deal , I am all in for it but there is problem that it runs i7-6500U processor which is latest but has only dual core .. which is very big let down for me. Please give you views, should I go for it or not ?

My advice is go for it. It is not only most recent CPU from intel but also most power efficient. The laptop will give you best battery backup with most power available. If you are worried about its 2 cores then should see comparison. In raw comparison between recent 4 core 6 core i7, you will find them better. This CPU is for more balance between power and powerconsumption than just raw power. Hope that helps you to make your decision.
