I need a new gaming laptop?

I'm looking for a new laptop. I'm a hardcore gamer. I play for around 80% of the time that I'm awake. I currently have a Lenovo y510p.
Specs:
Processor: Intel(R) Core(TM) i7-4700MQ CPU @ 2.40GHz (8 CPUs), ~2.4GHz
Memory: 8192MB RAM
Card name: Dual NVIDIA GeForce GT 755M SLI
Disk Drive: 1 TB HDD

I'm looking for a nice new laptop for under $1400. I have been looking at MSI and ASUS. I don't know what to get. I'm looking for a far better laptop than the Lenovo. Please leave a link to some good laptops please.

Which laptop should I get for gaming?

AMD A4-4300m with AMD Radeon HD 7420g graphics 6GB ram and 750 gb space. Or Intel core i5 4300-u with Intel Hd graphics 4400 with 8 GB ram and 500 gb space? They are both at the same prices at 480 dollars before tax and the thing is I need a laptop because I go outdoors to the park a lot with family and other places and want to play games like Skyrim etc, so am getting a laptop instead of a Desktop. They both have good rams and pretty good hard drive space for me, now I don't know about processor or GPu, the processors can go to 2.6-2.8 ghz when focusing on a game which suffices for the games I have in mind, but the Gpu sucks.
I plan on playing: Titanfall, Battlefield 3, Skyrim, Final fantasy 14 a realm reborn, Splinter cell blacklist and some other games too which all of these aren't big games (in terms of requirements) and I don't care about graphics even if I have to play on low, so Can any of these laptops play these games on low-medium and which one is better?

Asus G56JR or Lenovo Y510P?

Even after putting hard efforts to find out which of these laptops (Asus G56JR and Lenovo Y510P) is the best, I'm still not sure.

Rather questioning in a technical point of view I'll list down what I need:
1) i7 (4th generation)
2) 8gb RAM
3) 1TB Data
4) Stunning Sound
5) Durable
6) Good Sound card
7) Not the best but a really good graphics card
8) Suitable for music production
9) Suitable for College work and etc
10) Affordability

I want to keep this laptop for at least 2 years.
I need it for all purpose which includes music production, gaming, education and etc.
I live in India so I would be glad to get answers on the basis of that.
Please I need a straight verdict have very brief reasons.

Lenovo y510p internet issues?

I bought my lenovo y510p 2 weeks ago. The internet was fine for the first week or so. Suddenly my laptop disconnects from my internet once every 5 mins or so. It's incredibly stressful to deal with this. I'm a competitive gamer and i bought my laptop for 1300$. I did some research and heard that the Intel wireless adapter is an older version. Do i really need to buy a new part for my laptop? And is anyone else having this issue. Sorry if i'm using bad grammar and sold a bit rushy. I wrote this earlier and it crashed while i was posting and i lost it.
