does graphics card improve pc performance, apart from the gaming experience? i am thinking to buy a new graphics card. my pc is intel core 2 duo, ram- 2gb, motherboard- gigabyte. please help me.
Apart from gaming there will be little or no performance increase except a few specific tasks that can use the graphics card. Your PC is a bit dated so it may help if you cannot play films smoothly it will help and may free up some shared RAM but nothing significant.
Not really. It only makes things that are graphics related faster, like gaming, 3d modelling, watching movies (only faster up until the point movie is smooth, it won't get better after that point). For general windows use it will do absolutely nothing. You're better off getting an SSD, that WILL boost the performance insanely.
