Congrats on your new parts :thumbsup:
That looks like a solid monitor in that price range. Amazing how it's now possible to buy an IPS 2560x1600 25" and people are still sitting on 21-23" 1080P.
I'd vote for GTX980 4GB. It's doing fine over 1440P, of course taking into consideration a current reasonable price compared to newer models.
That card sits in 'no man's land' for 1440P or 4K gaming. It costs $100 more than a 390X and has almost nothing to show for that $100.
Another way to look at it, the 980 at retail costs $200 more than a 390/970 but for $100 over the 980 it's possible to get 970 SLI or 390 CF. Either of the latter setups will blow the doors off a 980 at 1440P. 980 primarily makes sense at EVGA B-stock prices imo but at retail $480+ prices it's a horrid buy since some 980Ti cards are $610, while EVGA B-stock 980Ti is
$550 right now.
I am in need of a new vid card, want to get away from 1080p. will be playing Guild wars 2 I think didn't have he time to retry the game much before my vid card died. I have witcher 2 also but may not play the game much depending how much I like Guild wars 2.
I want good frame rates and a Monitor that I can use for a long time. Don't see wear 4 k will be cheap enough and have the card to drive it good for some time.
It's possible to get a 40" 4K for
$600 US. This monitor might get FreeSync in the future via a firmware upgrade.
It's also possible to get a 28" 4K one for
$650 with GSync.
Since you are aiming for 1440P, you can start researching
here.
Personally, every monitor I've owned I've had for at least 7 years and since the monitor can be enjoyed for movies, work/productivity, etc. it's something I would spend more $ on vs. a videocard that becomes outdated/obsolete. Chances are you will upgrade your videocard 2-3X over the lifetime of the monitor. As a result, I would much rather buy a $700 monitor and a $300 videocard with your budget rather than a $350 monitor and a $650 videocard.
Just to give you an idea, a $700 GTX780Ti came out November 2013 and that level of performance can be purchased in a $260-280 390/970 barely 2 years later. The same will happen to a $650 Fury X or 980Ti. Unless you can afford to buy $650 cards every 12-15 months, I personally don't think they are worth it if your budget is $1000 for both the monitor and the GPU. Sure, there will be monitors better than what you can buy today but if you buy a $700 monitor today, chances are it will be really solid for many years to come, while a $650 videocard will become a $350 performance level by end of 2016, and $200 performance level by end of 2017. It's not going to be possible to buy a $200 monitor as good as a $700 monitor today by end of 2017

You should first figure out what display you want and go from there. I think that would make it way easier for you because a good starting point would be a $280-300 290X/390/970 level card as those are more than enough for the games you listed and generally speaking provide the sweet-spot in today's market.
Above that point, at retail prices, 980/Fury/Nano make no sense over those as they won't give you enough performance increase at 1440P to warrant their price increases, while the next level up is $650 980Ti which starts to dramatically cut into your monitor budget.
Just my 2 cents.
