Here is the pricing of all the brands I enquired (For GTX-650Ti Boost 2GB):
1. Gainward: 12.2k
2. Asus: 13.6k
3. Palit: 15.5k
4. MSI: 14k
6. Zotac: 13.3K (only @ flipkart, Stock is not availabe in India now)
I am actually looking for Zotac, it was availabe at flipkart earlier at a much better price, almost ~12.3k. Both MD Computers and Aditya Infotech say stock for Zotac is not available now and fresh stock might take a week or two to come here. So, I am thinking of waiting for the time being, else Gainward is my last option.
And guys if you find any good deal in the meanwhile, please post it here and let me know.
