Hi
I'm about to buy a gaming laptop. It is my first one and will be used for photoshop, premiere pro editing, games ranging from GTA5, Batman Arkham Knight to Witcher 3. All high settings, none Ultra. I have shortlisted two laptops from ASUS. They are

ASUS GL 503
core i7 8th gen 8750H (30% faster than 7700 HQ)
NVIDIA GTX 1050Ti 4 GB

ASUS GL 502 VM
core i7 7th gen 7700HQ
NVIDIA GTX 1060 6 GB

Both laps come with 16GB RAM and 256 Gb SSD, The screen on the 503 is better, but the 502 costs a bit more here.
Please suggest me a good one.
