Tough question to answer, I've not brought an AMD card for years and I've never had an issue with NVidia drivers.
So I guess yes? but its not in stopping me buying an AMD card, but stopping me not buy an NVidia card.
That may change with the 390x, assuming all the facts in the 390x thread are true in that it will have 500% performance increase over everything, is hand delivered by Scarlett Johansson and Emilia Clarke and comes with a IOU and a direct line to God.
Still... every time I look in the AMD driver thread it doesn't fill me with confidence.
It's not a tough question to answer man. It's kinda like that skit in Viz with the kid who has a moped that runs on monkey semen.
It was fast and looked awesome, but where do you find monkey semen?
Hardware without good software is useless. This has been proven so many times over the years so I'll give a few examples.
Physx PPU. This worked for what? two games. No one supported it so it was sold to Nvidia and integrated onto their GPUs. IMO it was a waste of money.
Lucid Hydra (two revisions of). Ever heard of it? I doubt it. It was a chip integrated on certain motherboards that allowed more than one different brand GPU to work with others. As I predicted Lucid couldn't keep up with the drivers and it died a horrid death.
Xeon Phi. Fancy a PCIE device that adds 60 plus cores to your rig? no, me neither. Again, no software. You can pick them up for peanuts on the auction site because they were a total flop.
Intel Itanium. Great idea, no one could be arsed, in the grave it goes.
And most notably - Voodoo SLI. 3DFX made cheaper cores than Nvidia so could offer them in mutliple configs for far less money. IE - just before they died they made the 5000 series with two GPUs per card and the fabled 6000 series with four GPUs.
No one supported it. Had they? they'd have kicked Nvidia's arse but once again, no software support no dice.
I bought two Voodoo 2s and linked them up and added a 3Dlabs Oxygen as the main GPU. Know how many games supported it? none that I know of. Total waste of money.
Just look how long it took Nvidia to take that tech, refine it and get support for it (SLI that is). It took them about a decade, and that's only two cards. Three and four? are still not officially supported in game code so the drivers have to bodge it which is far from ideal.
