Defo worth upgrading much much slicker bit of kit the way it goes between game to apps silently and quickly the in game ddr (record you game play) is great I use it for 4od, youtube, netflick and gameing mostly
Forza 5 very impressive a good reason to buybit alone I recon
Battlefeild 4 64 player and titan fall all good reasons
Plus now its been out a while there has been lots of tweeks/patches to console and above games that you condole will get on set up so thats better
On the down side I miss the xbox 360 arcade section
Loved games like deadlight, the walking dead (tell tale games) but tiz a small gripe
