If your laptop will be dedicated mainly for gaming, I would suggest getting 17.3" one. Your proposed resolution 1366x768 is really low,
I would try to find one with 1600x900 (or 1920x1080 which is more than enough).
As far I am aware, the i5 processors will work better than their AMD equivalents (4 cores AMD is having is totally unnecessary and does not give any performance benefit over higher clocked intel processors, especially for PW).
Integrated Intel HD graphic card 5000+ is just fine as the graphic goes, laptops don't need dedicated graphic cards, unless you're aiming for a mid-high end.
Also touch screen seems to be unnecessary feature.
if u wana gaming laptop u need about 2k $
You can get a decent gaming laptop with just a little over $1000.
Laptops below that price can still do fine though, you just probably won't be able to run modern games at higher settings.
