Best Card in 10000rs

Yeah Madn3ss795's choice is good but save some money for a 650 ti boost cause u get 2 gb of vram plus get 192 bit buswidth instead of the 128 bit.you get nvidia's gpu boost technology which dynamically higher the clock speed for more performance out of your gk 106.
 

For your information galaxy is a very reputed manufacturer of nvidia based graphics cards.Their gc versions are clocked quite the same as the zotac amp models.
