I bought a Palit card out of desperation when the 8800GT was more scarce, and in terms of build quality it's fine. But I think that's true of all the reference cards.
Back when I bought it just a couple of months ago, their warranty policy was to send it back to Hong Kong, (unless you bought it from a reseller, in which case they instructed you to deal with the reseller), but now they've updated their website with an actual RMA form. Maybe you still have to send it to Hong Kong, I don't know, but all things equal, given a choice I wouldn't choose a Palit over an XFX or EVGA.
