Given the fact that XFX offers Double Life Time warranty that could enable you sell the card easier down the road (when needed) as the buyer will also get a warranty making them less hesitant to buy a used card.
Double Lifetime Protection*
Nothing tops our warranty. It’s not just a limited lifetime warranty, it’s a transferable lifetime warranty. So, should you sell your XFX 6-, 7-, 8-, 9-, GTX-, GTS-, GT-, and GeForce Series or any XFX Radeon HD Series cards, whomever you give it to or sell it to is protected, as well. Better still, it’s the best card on the planet for gamers who push our cards to the limit.
As far as quality goes, XFX and Diamond both make quality cards, but in my personal experience, the EVGA and XFX cards tend to OC a bit more than ASUS,etc cards.
