Well, I think nVidia does have some work to do with the new APis. However, I also think all this talk of making a purchase based on what *might* happen, especially based on a single AMD Evolved game, is pretty absurd as well. Especially for a midrange card that can easily be replaced in a couple of years.
Doom is brand agnostic. AMD working closely with the developer to take full advantage of GCN in no way precludes NV from doing the same. There is also no AMD black box equivalent GW source code that NV is forced to render. No one is purposely gimping or stopping NV from using Async Compute they touted in Pascal. The older generation cards cannot use this feature since they don't have it.
I am pretty sure if Intel worked with a game developer and optimized the game to run way better on Haswell or Skylake over Sandy/Ivy/Bulldozer/Vishera, the same people moaning about GCN smashing Kepler and Maxwell in DX12/Vulkan wouldn't say a word about "unfair" optimization practices.
As far as people calling out AMD on having better longevity, I don't blame them as that's just a fact. Even if we ignore Doom, in EVGA 1070 SC review by TPU a $700 780Ti lost to the $400 reference throttling 290 @ 1440p. Look at 780Ti vs. 390X to see the whopping 780Ti is getting now against the card it was designed to go head-to-head. Look at how horribly 680/770/780 fare against 7970/280X as of November 2014!
It's also amazing how you keep defending NV while getting offended when people show proof that GCN was the superior architecture to Kepler and Maxwell for future games, despite yourself using an HD7770 for almost 5 years. NV has put your card's competitors on legacy support while AMD still puts out drivers and performance optimizations for your long outdated card.
Practically almost everyone here who recommended Kepler and recently 750-750Ti/950/960 should be recommending 480 over 1060 simply based on how bad their advice was over the last 2-4 years. I still remember the cries over 2GB and 3.5GB as sufficient but now the same people are trashing the 480 4GB. The bias is so obvious that it's a shame because many gamers come here for an honest advice.
It's gotten so bad that now that the price/peformance metric is flat out ignored. We literally had guys on here doing anything to not recommend 280X/380X/290 over the 950/960 now suggesting gamers should spend $50-100 more for a 15% faster 1060 over a $200 480. Let me guess what's $50-80, just a meal for 1-2? Ya, that's why on Steam so many gamers have an R9 290, right?
