Naw, I paid cash for them. The worst part is the only stipulation, according to the box, is they must be registered w/i 30 days, it says nothing about proof of purchase. Both were registered, because neither of them came with the Crossfire ribbon cable or other *supposedly* included hardware. So, they were registered within 30 days of purchase..
Visiontek, I found, is notorious for doing this. They offer a lifetime warranty simply because they refuse to back it up. I've read on other forums people are actually trying to coordinate filling a "class action" lawsuit against them. Splitting the initial legal costs up between different customers who've been shafted out of a legit warranty.
One guy even sent his card in for RMA... Visiontek claims they lost it while moving to a new facility, and basically told him, tough luck we're not liable... Shafting him out completely. Total B.S...
