=>i'm guessing its 50k INR [Indian rupee]...u will need at least a 660ti/HD 7870 for a medium level gamming pc as Ramzzz said.
=>If not a nvidia fan give a look at HD 7850 and HD 7870 too. And everyting else depends which games u want to play.
#cabinet - zebronics reaper or i ball velocity=4k .which will be better?
