First i was willing to buy nvidia gt 640 but after viewing reviews of amd hd 7750 i realised that its the best and cheap card in the market so can u inform me that will it run future games like bf4 on mid or high settings without lag and how much fps it will give on crysis 3?But its just a little bit expensive will i get my benefit for purchasing this product?My processor is core 2 duo and 2gb ram 32bit win 7 450w psu
