Sangeet Khatri :
Can I please know that why are you not comfortable in buying a 20,000 Rupees GPU? I mean it is the most important component when it comes to gaming. Other than that you have got everything covered, now you just need to spend more on the graphics card.
The 760 should be the one you should get as it is within your budget and it is much more awesome than the 7870 or a 660 or even a 660 Ti.
Please, go for the 760. You would be much happier with that.
I am not too comfortable with the concept of a 20000 GPU because, well I don't know, I think I'll be using my computer for single threaded stuff a little more than multi threaded( I am assuming that single threaded means Web, Youtube, Torrents; and multi threaded means Games overall). I don't mean that games will be like once every 2 weeks or anything. Also, the concept of a Rs.20000($330) GPU is just plain crazy to me, because I'm not that intense of a gamer.
Also, the link you mentioned in your previous solution is for the 660. I'll be ordering all my parts from flipkart, and on flipkart, I found that a 760 costs 21-24000: Just not gonna happen(My mind is wired that way).
So now it's between these two:
ZOTAC NVIDIA GeForce GTX660 2GB 2 GB DDR5 Graphics Card- 18000 or $296
OR
XFX ATI Radeon HD 7870 2 GB DDR5 Graphics Card- 17000 or $280.
Between these two, price is not a problem. The only problem in my mind is that the Zotac cooler will stand out(Orange color) from my Blue lighted interiors =bad. But however, for these prices, I don't think that matters much! So, please tell me the name of the one which has better performance overall. If any, please state the difference between AMD and Nvidia, specifically between these cards.
In the end, I want the biggest bang for my buck!
