Thanks for the input!
Just wanna say something about lagging (not input lag, but ordinary lag).
It´s very much about what you have installed, and what processes being run in the background. I have used Titanium Backup to wipe a lot of bloatware, and when I´m gaming, I use Astro to kill off all the unnecessary apps being run in the background.
I always run Task-Killer in Astro prior to gaming, the experience is much better.
