UX12: All I really care about is if it'll run just as well on AMD cards as an equivalent Nvidia gpu.
The amount of nvidia software tech being used is worrying.
RudyLis: Imagine CDPR giving everyone AMD user a free GTX 980 card. :D
Trilarion: Just for fun I was curious what a desktop PC with the recommended settings would cost me currently:

RudyLis: I did the same for apparent "almost constant 60FPS on ultra". MoBo, CPU and GPU alone cost as much, and full rig will be somewhere around $1700. Not bad for "almost constant 60 FPS", eh?:)
RWarehall: I don't have an article on it, but what I do is go by Benchmark charts like this one...
http://www.videocardbenchmark.net/high_end_gpus.html Even if it isn't perfect, it gives an idea where you might be at. That site also ranks CPUs.
RudyLis: Problem is that these ratings do not always represent head-to-head performance in applications (and I don't mean gaming only). According to that site, GTX 970 outperforms R9 290x at about 20%, yet real tests we've performed do not support that (as well as some Internet hardware review sources). Green one may be faster for certain games and apps, yet it may be slower (and much slower even) in another, and in most cases we speak about single-digit FPS value and milliseconds (not even seconds) in terms of work applications (CAD and other suites you can find in construction industry). Not sure famous 3.5Gb issue is the case, really. I can't say what's the problem, either those specific Nvidia GPUs we bought for tests, or lack of any real advantage, contrary to every consultants' opinion, but I don't really see that "power overwhelming" from GTX.
Sadly we, ordinary gamers, do not have an option to buy several various models to select proper ones, and relying on internet sources may unearth rather unpleasant surprises, like that one with 3.5Gb VRAM case - how many reviewers reported it?
As I said, its a guide and I did mention ballparks.
For Witcher 3, GTX 660 is minimum (rated 4118) or an AMD 7870 (rated 4257)
Recommended 770 (rated 6148) or a R9 290 (rated 6561)
The poster had a 840M (rated 841).
Clearly that will not run the game. I surmise that one might have a chance to run it with a card maybe in the 3,000's with luck.
I provided it more as a reference to how the weird NVidia numbering system works in comparing one generation of card to another among the different models as well as mobiles to desktops. I agree, benchmarks are likely poor comparisons between AMD vs NVidia at times, but should give a decent idea how different cards might rank vs, one another from the same manufacturer.
