martineverest: lumia 1520 and 920 are kings of mobile gaming.

COPY THAT. NBA JAM all day, LOL.

Anyone who has used a Lumia 1520 (which uses the SnapDragon 800 and has a 1080p display) will tell you that it blows the little A8 inside the Iphone 6 plus in performance. Web browser scrolling is atleast 4x smoother and faster.
AND Lumia 1520 has significantly better battery life.

SO DONT LIE AND SAY THE A8 BlOWS THE SNAPDRAGON 800 BECUASE THE SNAPDRAGON DOESNT COME IN A 1.32GHZ DUAL CORE Snapdragon 800 is A BEAST with >2.3GHZ QUAD CORE WITH ADRENO 300

And as far as Windows Phone 8.1...The nexus 5 has the same exact processor and even it is beat by the Lumia 1520 in benchmark. Better performing drivers.

AND THE SNAPDRAGON 800 is >14 MONTHS OLD
