well in my country,660 costs almost the same as 7850...so shud i stick to 660 den?
The 660 is a nice card, if it plays the games you wanna play at good framerates & you like Nvidia and the Gigabyte card, I say go for it! But if you don't really know what you wanna play & all, I would recommend searching both GPUs & their results in gaming, then take into consideration whether you want to overclock or not, and then check if it's good for your needs. If you wanna do 3D, Nvidia is the best. If you wanna do multiple monitors, AMD is the best. Just look at performance & then decide from there, okay?
