I think it's quite clear that if you had to (for whatever reason?) only include one mode for the 290X that it would be better to include Uber since most enthusiasts will chose this mode for playing games. There is no room for minterpretation: enthusiasts that buy the 290X reference will game in Uber mode most of the time. Does anyone actually disagree? Honestly?
Now, I don't mind seeing both Quiet and Uber. For the reader, this is more data and is better. But I understand that the reviewer is a busy man. But, choosing only one mode, and picking the mode least likely to be used by enthusiast gamers? Wha?
Now about that 290 review:
More importantly, I think there's too much personal feelings coming out here. Ryan demonstrated rather openly that he feels a product being louder than its competition is all that matters. Ryan thinks sound is ALL THAT MATTERS. I can't wrap my head around this. AMD offers a solution that is $100 cheaper than the 780 and wins on performance. But instead of it being a debate about the values of price-to-performance vs loudness, Ryan makes a harsh and extreme judgement: you cannot buy the referene 290. It is too loud to own, regardless of your case, regardless if you use headphones, regardless if you plan to use the $100 savings to invest in liquid or nonreference cooling. It is untenable as a purchase because Ryan, personally, has strong feelings about noise. Strong feelings that were not there in 2010.
The fact that there's an entire thread about bias is telling. I honestly don't think it's anti-AMD bias. Although it's odd since he was fine with it in 2010, I think it's just a sound thing. For whatever reason, the man has VERY strong feelings about noise. Ryan is evoking a great deal of emotion in his anti-290 series actions, and it stems from some kind of traumatic experience with noise - something that has happened in the past 3 years.
I would just ask him to consider that he has these strong feelings, and to try to seek a more balanced approach.
