Which should I go for?

I'm a high school student and I'm looking for a gaming laptop that will last me for a long time. My parents set the budget at a max of 40K PHP so thats' about 860 USD. Since electronics here in the Philippines are overpriced, these two were the best specced in their price point, maxing out my budget. Which of the two should I go for? I play CS:GO, CoD: BO (the first one), GTA IV and it's expansion packs, and maybe GTA V. Assassin's Creed III doesn't hurt also. I also do the common tasks on a laptop like browsing the web, watching videos etc. P.S. I can't upgrade anything in the future, and also if you're wondering, the base configed Inspiron 7559 here is over a thousand US dollars.

Dell Inspiron 14 7447

How about the performance of the R9 M275 and the 850M? Is there a significant difference between the two?

A wee bit out of topic, does it have really to be a laptop? If you need more of a gaming machine, going for PC will give you a lot better price/performance ratio but you will loose the mobility aspect.

The i7 is actually a dual-core, and the i5 on the Dell is actually faster..
