i got an RX460 4G from gigabyte. I mostly play CS:GO and Battlefield 3 on an 1080p Monitor at maxed settings with way above 120 fps( i think it was in csgo mostly around 200- 300). I also tried Battlefield 1 Beta and it did run smothly, but i think it wasn´t maxed out. So maybe you have to sacrafice the ultra for high in some new games but otherwise it´s a really good card for the price.
Blade 14 or Blade Stealth... man that is a hard decision. Both great machines.. but wait, was there something with4K screen and 100% RGB coverage? I would take the Blade Stealth, just because of the Screen.
