Hi, i am playing COD -Advanced Warfare but with my current rig i am barely making it run on my system by the skin of it's teeth,i have to play the game at the lowest settings possible but still it lags at high graphics areas.As far as i know about computer i am sure the only thing letting me down is my graphics unit which is a nvidia gt 610 2 gb ddr3.....besides that my rig includes a amd fx 4300 4ghz quad-core black edition and a 8 gb ddr3 ram with a 1tb hdd. I want to play these next-gen games anywhere between mid to high setting but my budget is for a graphics card is not more that 11k. Can anybody suggest me a graphics card for this preference which can run on a smps of 550 w to 600 w
