I recently purchased "Asus NVIDIA GTX660 TI-DC2T-2GD5 2 GB GDDR5 Graphics Card" worth Rs. 22300 from Flipkart. The moment I opened the cardboard cover I saw that the box was squished. When opened the box to see my graphic card I saw that there were finger prints all around implementing that it was opened before or may be used. I ignored all of the above and installed it on my computer. The graphic card is not working. I even went to a computer expert and checked my system, he also said that there is something wrong with the card. When I remove the card from my system, it run perfectly fine. Whenever I try to connect the card it fails to provide any display or even boot-up. I previously had MSI NVidia 560 TI installed on my computer and it is working perfectly fine. I have a 500W cooler master power supply which is more than sufficient for this product.
I called Flipkart for help and I was told that I have to go to service center and have get it fixed. Remember the card is not even a DAY old. I emailed flipkart and they told that my system is not compatible. I have the a i5 process and the latest Z77 motherboard. My friend is ruuning the the same product with lower specs than me. I even sent them the manual from NVIDIA website which clearly states that the card is fully compatible with my system. Still all my money was wasted.
NEVER BUY ANYTHING FROM FLIPKART IF DONT WANT TO BURN YOUR MONEY
