I would swear there was a *huge* fuss many years back between Hexus and nvidia over what benchmarks and settings to use and not to use. Can't find any of the details now (the web appears to have been expurgated, or my google-fu is weak
) but
iirc it end up with nvidia refusing to send review samples to Hexus for a while. Then again, I could be remembering wrong, or it could've been a different review site. But these things do occasionally blow up.
That said, it does seem to mostly be nvidia who kick off about such things (remember their claims a few years back that AMD were deliberately reducing IQ in the drivers to get better performance?) while AMD let consumers make their own mind up, and I don't think it's particularly damaging to AMDs bottom line to let nvidia have their rants occasionally. For some reason nvidia seem to attract a slightly more frothing variety of fanboy than AMD, so the forums & comment threads tend to kick off more against AMD than against nvidia (Crysis 2's bizarre over-tesselation, anyone?). I prefer AMDs approach, personally - concentrate on the hardware, not the spin/smoke/mirrors....
