Built it to for FPS and MMO games, was not disappointed. Plays everything I've thrown at it with no problems at all on max settings.
I get around 70 FPS on Battlefield 4 (Same with Battlefield Hardline Beta) with Ultra at 1080p with AA disabled.
The motherboard is great for overclocking and so is the CPU currently running it at 4.0 GHz stable with 1.26 Volts (Had it up to 4.2 with 1.29V) with 12GB of RAM in Triple Channel @ 1600 MHz. Another good thing about this premium motherboard is the ability to run TRI-SLI/Xfire configuration at 8x or SLI/Xfire at 16x if running just two cards.
Corsair M65 is freaking amazing plain and simple, The 1500 Vengeance has great positional audio and bass, mic is crystal clear.
Razer Goliathus Speed Edition mat is tremendous, soft and has excellent tracking!
The Gigabyte Windforce 3 OC 760 GTX is an absolute beast and I got lucky with an awesome overclocker :D
Power Supply is the Corsair 850W TX but they didn't have it listed on PCPARTPICKER.
