This is the 2nd time you misinterpret my comments. First you implied that I said all GF8 have failed and you proceeded to link working GF8s on sale. As mentioned by other posters, no one made a claim that all GF8s have failed only that all have inherent defects and can fail at any time.
Now you implied as if I said that anyone who bought NV in the last 5 years is dumb. That's not what I said. What I said is NV users who ignored mining are dumb. Why is that? Because you could use thousands of dollars made by AMD hardware to drown yourself in NV hardware from the proceeds. Your analogy would be if you purchased competing chips and the more you ate them, the more $ you would get to buy up to a lifetime of Doritos. For example your brother could be either gaming on a free 7970 now or could have bought a free 780Ti. Most people in North America ignored mining because:
1) They didn't even know about it (until too late)
2) They thought it was a scam
3) Too risk averse to spend $ to make $
4) Didn't know how to set it up software wise
5) Were too lazy to learn about mining, how to set it up digital wallets and convert to USD/gift cards
6) Loyalty to NV made it impossible to consider buying AMD cards even knowing that AMD cards made $
7) Didn't want to deal with the extra noise and heat. Although this one mostly comes from ignorance because you could have undervolted/underclocked the ASIC and purchased cool and quiet 7900 cards. Even 1 of them could have made $2-5K.
8) Have so much $, they don't care about making $10000-30000 in mining.
However, on our technical forum, I also saw that most loyal NV users who keep buying NV only have also ignored mining. This was shocking to me because most of the points I made above don't apply to them. We had guides on what cards to buy, what settings to run, how to set it all up, how to minimize your power usage, how to maximize Mhash per watt, etc. Guess what? Those who followed our advice are sitting on 4-5 figures of earnings and if they so choose can purchase many next gen cards for "free" over and over. Many experienced NV users put down Bitcoin mining and simply refused to be open-minded. This was not about buying AMD cards for many of us but about using PC hardware to make $ that we can use to buy things in real life, such as more free future PC hardware. Amazing perk and despite that AMD's market share didn't explode since 2008. This shows just how uninformed the average PC gamer is.
If you don't want to use mining as evidence that the average PC gamer is not technically savvy, JHH quoted that 80% of NV users didn't bother adjusting PC game settings/optimizing when he announced GeForce Experience on stage. That is more evidence how little technical knowledge/desire to learn PC hardware and patience the average PC gamer has. You think the same people will spend time reading extensive PC hardware reviews, follow-up reading reviews over time, visit forums such as ours or OCN or overclockers.net? Not a chance. You know 14-17 million AIB graphics cards are sold a quarter! How many of those people know squat about graphics cards vs. brand name?
I think what you are missing from the overall theme are times when NV was clearly the inferior choice. FX5000's horrible DX9 performance and IQ, 7000GTX horrible AA and performance in shader intensive games, Fermi's 6-9 months delays and 10-15% more performance for 80-90% power usage, ignorance of Bitcoin mining. All of these situations highlight how the average PC gamer perceives the NV brand and it helps us gauge his/her general knowledge of hardware - an average level and not much more.
The core NV userbase is very similar to that of any successful brand in how they think. Best selling Beats, Bose, Hondas, Toyotas, NIKEs, Coca Cola, Levis, Taylor Swift, Apple. These are all very strong brands for the average consumer. But it doesn't mean that they don't make crappy products/release poor content/songs from time to time. However, it is NV's brand name and blind consumer following that explain the lack of disastrous market share losses during FX5000 and GF7 eras, as well as during Fermi delays; and well the success of bad but hugely popular products such as FX5200/5500, GTS450, GTX550, GT630-640, 650-650Ti, etc.
