You need to add an option for "i dont own an XFX card" for the majority of members will vote the way they hear people talk about XFX if they dont own one themselves, most read the OP after voting.
that being said, have had an XFX 6800GT since the 6800GT line launched (got it the first 2 weeks) and have not had any trouble with it, but i dont overclock.
Also, please see
this thread , it is similar enough to this one and can provide you with a little insight.
