I own several video card that were bought over many years. In fact, 90 per-cent of my cards have been bought from abroad.
To those of you who worry about Video cards dying, all I can say is of the 13+ video cards in my collection over the years, NONE has ever died on me. All of them are still 100 percent functional.
Worst thing that happened is one of my cards developed a fan problem. I disassembled it, cleaned the fan and it put it back in and it never gave me a problem after that.
I would like to add that I always run my cards at stock. If I want an over clocked card, I buy a factory OC'd version rather than fiddle around with it myself.
Regarding Indian retailers/importers - I always find it amusing how local retailers/importers revise their prices upward even one day after a price hike/Re. drop despite the fact that items are currently in stock with them and were not part of the hike. However when a price drop happens, they want to first liquidate all their stock at the old price before they offer to sell items at the new lowered price like Sabby mentioned. Compare this to good stores abroad and you can see the difference. Maybe stores abroad are offered "price drop" protection? I don't know for sure but its quite possible.
My advice - if a card is about 25 percent above its US price buy it here. Anything beyond that consider getting from abroad. As long as you have a good PSU, decent cabinet ventilation and buy a quality GPU it wont let you down.
