Actually, GTX 680 took a few months just to be available and by the time it and the GTX 670 were available, Nvidia too still had driver issues, especially regarding V-Sync and some of their AA technologies. Furthermore, AMD took six months to get a decent driver, not over a year. That's bad, but not nearly as bad as you're makign it out to be nor is it important right now because they already have good drivers now.
VCE was not a big deal and still isn't.
AMD adding game-specific updates is not a bad thing. Nvidia has been doing it too.
Older Fermi cards almost never perform nearly as well as current GCN offerings even for workstations except for CUDA where AMD isn't capable of doing it because Nvidia made it proprietary and doesn't share in any way. Furthermore, a lot of Nvidia's Kepler cards lose to the older Fermi cards in many workloads and it's not because of a software compatibility problem either.
ah, you're adding card availability. that actually makes the case worse for amd because amd's gcn cards were available for much longer (than kepler cards) in retail before driver support was added let alone higher performing drivers.

they do have competitive drivers
now, but overall software support is still sub-par. i haven't even started on what they did to their mobile drivers, enduro etc.
i can't tell you how bad it was back then because the launch driver problems were enough to keep me from buying them.

iirc, pitcairn based cards' release boosted gtx560ti 448 and 570 sales for 'some reason'. after a while, nvidia smugly introduced a deal on gtx480 cards to compete against 7850 cards.

vce's not a big deal? amd themselves hyped it calling it quick-sync killer. after release, nothing. i guess it's not a big thing if amd can't do it.

at least nvidia's nvenc had some crappy support - better than nothing.
older fermi cards shouldn't be close to gcn cards in terms of performance. gcn has better hardware, compute-friendly architecture, everything except software optimizations and some much needed and much deserved attention. kepler is segmented for gaming and compute. nvidia still makes pro cards based on gaming asics - that way they can sell two pro cards (leveraging maximus
software tech) instead of one - yet another trick that makes nvidia more money.
