I gave 1200 dollars for a mini itx gaming pc. I need to be able to run all new games on high to ultra. Nvidia graphics only. The case I want is the bitfenix prodigy any color. I also want Windows8.1 please. I don't need a mouse or keyboard. 8gb ram or more please. Mainly going to stream and play watch dogs, far cry 4, DAYZ, arms 3 and the upcoming gta v.
