I currently own an XFX 5870, and could always use an upgrade .
I like their double lifetime warranty and the fact that their graphics card hasn't given me a single bit of trouble in almost two years of owning it. I would like them even better if they gave away all their products for free, but unfortunately no known economic model currently supports that business strategy.
I like XFX for the lifetime warranty and the 6990 is an an awsome all in one option for eyefinity! win/win. If it was anymore winning, Charlie Sheen would be on it.
