Which of these three gaming laptops should I buy and why?!

[Seabee013]

•Dell ANW15-7493SLV 15.6" Alienware Notebook Computer
[Perks] -4k Resolution -Touch screen (though I'm not sure I can see myself using it. Maybe for photoshop but it would be weird not having the 360 degree tilt) -More mobility (Barely)


•Dell ANW17-2136SLV 17.3" Alienware Notebook Computer
[Perks] -17.3" display @ 1080p


•ASUS ROG G751JT-CH71 Gaming Laptop 4th Generation Intel Core i7 4710HQ (2.50 GHz) 16 GB Memory 1 TB HDD NVIDIA GeForce GTX 970M 3 GB 17.3" Windows 8.1 64-Bit
[Perks] -17.3" display @ 1080p -Blu-ray Optical Drive

I don't play many heavily demanding games but I definitely need a upgrade. And I want something that will last me a while and have the option to keep up with newer games.

P.S.-I will be saving 25% on any of the three models.

GO with Dell ANW15-7493SLV as it will perform similar to the others and will be more portable.

That's what I was leaning toward most, ordering it today. Thanks!
