Interesting commentary regarding 290/390(X) and Maxwell. Not sure why each side has to poo-poo on each other. Having owned both (sold my 290Xs, currently with 980 Tis) and having no blind brand loyalty, I must say they are both really great cards.
As a consumer all I really care about is whether the GPU I own does what I need it to do. The performance of another company's GPU I don't own doesn't bother me and it shouldn't. Just because one GPU does well doesn't mean the other GPU sucks, especially if they both are capable of doing what I need them to do. And in this case, both are doing really well with great frame rates with high levels of detail.
Yes, DX12 allows Hawaii to perform better than it has before, giving its its owners high levels of performance long after its release. I see that more of an great thing for Hawaii and not really a negative thing for Nvidia. On the other hand, GM200/GM204 is still offering great performance in every game out there today, DX12 or not.
So with this new world order, isn't this a great thing for everyone? Great framerates with high levels of detail no matter what side you're on? I don't get all the negativity.
There are OBVIOUS differences between the 2 cards though.
It's not about pooping on either card or being on a "side". If you're on a side, I just feel sorry for you.
It's about looking at the straight trends and figuring out where you fit in.
I don't ignore facts. I wanted a GTX 680, I ended up with an HD7950. I wanted a GTX 980Ti, but I ended up with a used R9 290. Right now, when it comes down to getting the very best bang for your buck it's AMD.
It's not about loving AMD, it's about getting the best value for my money. The way the market works right now, as long as AMD is "Behind" Nvidia, they need to gain marketshare, and thus generally will give better value for the money. They HAVE to get people to buy their products.
Look at Fiji... do you see anyone pushing fiji talking about how amazing it is? Not really. The bang for buck STILL isn't there.
It's not about love or hate of any vendor.
Below this performance bracket:
Used:
GTX 950(New) if you have a 4K HDMI2.0 TV you intend to use,
otherwise, just get something used, which will most likely mean AMD because they don't hold value although the 290 has actually gone up in value recently and I can sell mine for more than I got it for).
Used R9 290(GTX 970 isn't really a good choice here, they hold too much value but if you see a good deal or a good EVGA deal on a refurbished unit jump on it)
Refurbished GTX 980 EVGA (Just a good deal... so ya)
New:
R9 390
GTX 980Ti
It's BOTH vendors. There isn't bias. Get over it.
It's been said by many users here.
But the truth still holds, it does seem the future does have a LOT of console ports which seem to do better so far on AMD architecture so if you want to make the best "bet" for your purchase so far, it's an AMD Hawaii card, and we'll see with Polaris/Vega.
Right now, there is 0 case to make to recommend or believe Maxwell/Pascal cards will do well in a world of PC gaming in which we're looking at console ports. That's just a fact.
