So you crossed off AMD GPUs off your list because the known to fail XFX 5870 let you down? Not sure I get that since we have people on our boards with failed 570, 670 cards, etc. Should we talk about the utterly horrendous GeForce 8 that was a ticking lead-free solder time bomb? I bet the failure rate of GeForce 8 is catastrophic over 5 years of ownership. This is not like 1 vendor producing crap but ALL mobile and desktop GeForce 8 cards. Every single one can fail at any time since they are all flawed.
Also, $1000 Titan, $650 280, $650 780 leave a negative association for me with NV, not positive. To you NV selling $1000 Titan and $3000 Titan Z is good brand image, but to me it's arrogance, rip off milking cows, and greed.
It's like they want me to bend over for marginally faster performance? 980 for $550 when I can get nearly 2 290Xs for that price and send 980 tonthe grave in 90% of titles (same with unlocked 6950s vs. a 580). For me AMD is like a Porsche GT3, gives me 90% of the performance of Ferrari 458/McLaren MP4-12C for a fraction of the price, minus the snov factor. Once a new gen comes out, I put the money towards a new card and move on. NV used to be like that with stunning cards like GeForce 3 Ti 200, GeForce 4 Ti 4200, GeForce 6800 GT, GTX460/470. Since GTX580, NV basically sent message to me that I gotta pay 50-100% more for 18-20% more peformance. It's not a little bit more, it's a lot more.
Frankly for me, NV wasn't even an option for the last 5 years since AMD cards made $ and I still bought 470s to play around with during the mining craze. But that proves the point of many posters here -- NV users will pay $1000 for dual 680s rather than get 7970s free. There are posters on this forum who will pay $1000 for GM200 instead of getting dual 390X for free. It's because of blind following of NV brand that AMD can release a card 2X faster for 0.5X the price, and most NV owners would still buy NV.
Look at horrible cards like 450GTS, GTX550, 650/650Ti, 750/750Ti. Sold like hot cakes and all of them were overpriced junk for 80% of their lives. People buy 750Ti for the same price as a 30-35% faster R9 270 with games included too. What more do you need to know?
Buying NV also no longer means bullet proof drivers or future-proofness. NV stops supporting their old cards like Kepler and they purposely make their cards VRAM limited so you upgrade to their next gen. In many ways NV is like Apple and JHH has praised Apple many times. He loves high prices, snobbery brand image, and closed/proprietary features and marketing tactics. I had the money to buy 580s and 780Tis since AMD cards made me thousands of dollars in mining but then I see how quickly GPUs become obsolete, so I see no point paying top dollar for 10-15% more peformance with NV. It's not like 4200 or 6800GT days where I could buy NV's 2nd or 3rd best card and get 90% of flagship performance. The company that consistently brings this now is AMD. I am glad I saved thousands of dollars since 2008 and lost almost nothing in performance.
I would say the market share reflects the average PC gamer well. They are not very knowledgeable, don't understand tech and buy based on brand name / marketing. I spent $0 on graphics cards from 2008, but how much has an NV user spent since then? That's all I need to know. I know I made the right decision, if anything should have bought 10X more AMD cards
