I am considering purchasing an XFX GeForce 8800 GTX, from Craigslist. I am concerned about purchasing it and it not working. I guess my question is, if I bought it and I had problems, would XFX cover repairing via the warranty they supply? The guy claims it's new and has never been used. When I asked about the seal on the anti static bag he claims that there isn't a seal on the bag. I haven't purchased a retail Nvidia board before, but I know all the Radeon cards I have purchased have had a huge sticker over the lip of the anti static bag, that made it obvious that it had been opened. Any thoughts would be appreciated, thanks.
