Yeah, like I've said; I'm still gonna wait but it's not looking good for AMD right now.

My thoughts on memory stem mostly from the fact that while 4GB may be sufficient on average today, it probably won't be in several years and I'm trying to build something that will last a long time. 1440p gaming is more taxing than people seem to realize, I've seen the benchmarks of most top-tier cards and when you throw in the post-processing effects and higher AA and draw distances, the FPS sinks dramatically.
4k gaming is still just a dream imo, even the Titan X performs only somewhat decently at 4k with effects enabled, probably won't be until next generation that we'll see single GPU's capable of 4k gaming, with perhaps even more generation until we can kick 4k ass.

Consider this.
No matter what you buy, it will be ousted by a better card by AMD or Nvidia within 6 months anyway.

If youre planning on using a 1080p monitor, just get the 980 and enjoy yourself, my old rig has two 780ti in sli and even at 1440p has no problems with any games, if however youre buying a 4k display, then you should be looking at sli not single card.

Not going with either, I'm buying a 1440p display, been playing 1080p for too long. Which is also why I'm looking for a card that sits somewhere above the GTX980 as a single GPU but not quite the overkill of an expensive SLi/Crossfire setup (and the mandatory issus that come along with it).
Yeah, as I mentioned above, 4k gaming on single cards just isn't an option for anyone, I have yet to see a single benchmark above 30 fps average with effects turned on, and for me higher resolutions without the possibility to go nuts on effects kinda defeats the purpose of a rig with great visual output capacity.

I know that there's something better coming all the time, it's like when people buy new smartphones...

But I'm getting something that kicks ass today and will hang in there for a few years, my current rig is already close to 5 years old so waiting another year (or even 6 months) is out of the question. I've been considering the GTX980 for some time, but was surprised when they suddenly dropped the 980Ti, though it would come closer to fall.

Will wait for more news and benchmarks from AMD though, but I'm not too keen on 4GB single cards right now, HBM or no.

Ok, I've picked up the TechPowerUp review of the 980Ti to make some numbers.

I'm not going to do that again!

As you can see, the extra 2GB of the 980Ti mean nothing. Both cards lose the same percentage when you up the resolution. It's GPU horsepower that matter the most.

Great! Thanks!

The 980Ti has the added horsepower as well, and like I've said before, the memory is more about future-proofing as I'll be using it for several years.

Dammit! The chart doesn't show as it should :-/.
I hope Trucks can fix that soon.

What I wanted to show you with that is that you'll have to tune down some settings because of the lack of GPU horsepower before the VRAM is the problem. And because of that, choose the fastest card available within your budget.

Edit: Yay! The chart now looks less messy.

Yeah, my budget is not an issue... Been saving about 12.000$ in about 10 months. It's more about how much it will cost me today versus how well it will perform in a few years before I upgrade.

Waiting for more from AMD, at least the Powercolor 390 looks fantastic!

for me i will wait for benchmark and comment from all gaming and PC site, after all nobody knows, and also the price is still fluctuating. So it's wise if  wait until AMD releasing it and tested.

Absolutely, annoying that AMD hasn't dropped any more details yet, you'd think that they want to show consumers what they have, especially since most of these cards are set to release in mere weeks. It seems like a waiting game beteen AMD and Nvidia, they're sizing each other up and pondering where to place themselves on the price charts according to performance and expectations.

AMD have always been known as the cheaper alternative but also the weaker and "most annoying" (as in noisy and sporting far more driver issues) but it appears that DX12 actually benefits AMD builds more, and tests show a few of the flagship cards of Nvidia running surprisingly warm during load. Who knows what might happen in the next weeks?

If AMD releases card that is relatively kind on wattage, performs only slightly below the 980Ti (kind of between that and the GTX980) but at a much lower price, Nvidia have a case to deal with and may be forced to slice the price already to compete properly. Most gamers are concerned with value for money before absolute performance.

I guess we'll have to wait and see!

IMO, The most important thing, between 980ti or 390x, is that you buy either a gsync or freesync monitor depending of your card, the ideal would be a gsync and freesync screen. 

Adaptive vsync screens are the future!
