hi folks, very soon i am going to buy a graphics card from flipkart...budget is around 15k...i can see two cards sapphire hd7850 2gb and GTX 660 2gb in that budget...i am really stuck on which one to get as HD7850 has a 256 bit bus and 32 ROPs where as GTX 660 has whopping 960 shaders but 192 bit bus and 24 rops and it seems perfomance wise GTX 660 is better at stock but HD7850 has better overclocking potential which will even it out i guess after overclocking...plz help me guys...for me CUDA and Phsyx is irrelevent...i only want pure gaming perfomance across all games
