So which card would u suggest to go for if in case I put in around 2k xtra...
The card that comes closest to being a budget performance card is the GTX660. If you look for brands that offer the cheapest reference build with no fancy cooling solutions, you can have it relatively cheaper than the expensive Asus DirectCU 2 versions. I think the Zotac GTX 660 (Synergy edition) is the cheapest variant of 660 you could get. Around ~12K rupees if you are good at bargaining. In-game benchmarks suggest that this card clocks ~45fps average @1080p for most modern games like Battlefield and FarCry. Anything less powerful than this is useless because even these 'modern' games have been released at least a year ago. All future game releases will demand more processing power.
If you have capped your budget at 10K rupees, then I would recommend buying used AMD Radeons and crossfire them, instead of buying a low powered new card.
