this pc good enough for 2560 x 1440?

Solution
Yes, you wont have any issues at 1440p with a 980ti paired with a very capable CPU and the screen you choose is probably the best one that exists at the moment.

Have fun playing! :)


Depends on which VR you will be using. But even highend VRs like the HTC Vive should work without problems, because it still has a lower resolution than 2560x1440.
It runs at 1200x1080 per eye so 2592000 pixels compared to 2560x1440 with 3686400 pixels.

So you're VR ready no matter which VR. :)
