New Laptop for Gaming

[Kezotar]

So currently I've been looking through some laptops which would give me a good gaming experience, tbh I do mostly play WoW, however other games do occur and I absolutely don't want to be held back by my PC when gaming.

So I've come to find a few which all sit at the same price, more or less..

Or the a bit smaller one: http://www.multicom.no/Multicom-Kuns...0042/p10630919

Or even the one with 4K resolution. Again, all PCs mostly have the same spec, difference is the size and resolution. http://www.multicom.no/Multicom-Kuns...0042/p10630725

However, is the third one much more superior in terms on both the CPU and GPU that it would justify 250 USD increase? And how would the size of the PC interact with the cooling solution. I'd assume the bigger, the easier to cool? Or am I wrong on that assumption and maybe is the size totally irrelevant to the cooling performance.

This is a Laptop that's going to last me for a while so I do go a bit overkill.
Thanks

Dropping the choice above found a new one.

This at least has 16 GB ram and pretty much the same specs, in addition to an OS AND is .. Asus.
However, I found this http://www.netonnet.no/art/data/barbar-data/skjermstorrelse/17-18-tommer/asus-rogg751jy-t7058h/210160.3004/
Identical, however price is more expensive. I tried to check the specifications, none were different. What do you think guys?

You probably found it already but here is a review

If you cant see any differences, take the cheapest one I would take the asus over the other ones.

I didn't the time to do that, read on the previous laptops, however I've seen a review by linus + it's basically the same with better ram. And .. brand. Haha. But thanks for the link.

Btw, do you know what the numbers at the end have to say? Example.
T7009H on the one you linked.
T7103H Cheaper link
T7105H Expensiver

They usually indicate different specs, such as 8gb of ram or 128gb/256gb SSD and other stuff. Asus could also use different codes for different countries.

Something I just thaught of, it could be a different keyboard layout (US vs UK or something like that) but the price difference seems a bit steep for that.
