The XFX Lifetime warranty is only available now at Best Buy in stores.
The reason it was removed isn't clear. There is no official statement, anyhow.
Some of the techs here have some good theories, which combined make a pretty good case as to why its probably gone though.
My favorite theory was GPU's for profit/mining. The warranty was meant to protect gamers from gaming related failures that could be manufacturer defect, but instead, people were buying hundreds of GPU's and farming them for bitcoins/altcoins... which at first wasn't a problem, even running at 100% load for months on end, they did well... but then the bios flashing/modding (voids warranty, hard to prove) of the cards for better hashes and lower wattage started... then we started see RMA's of 10-25 units at a time, for $300 graphics cards... and it was insane.
We were familiar with getting 50-100 units a week, 1 card, 1 customer, 8+ years non stop (of course it varied). Very rarely we'd get 2 units from 1 customer... then literally over a few months, dozens of huge RMA's came in and i think that's what helped finalize the decision, or atleast get the conversation started.
Anyway, the XFX Lifetime Warranty has always been something we have been proud of and seeing it go really was a sad moment for us all. Alas, Best Buy still has it, so there's that.
Mark.
