I am considering buying the following computer:
LENOVO Legion C530-19ICB, i7-8700, 32 GB RAM, 256 GB SSD + 1 TB HDD

(Last weekend ~ Mostly 10% discount, the part was available for CHF 1'100.-)
Or would gamers recommend something else, I don't like to build it myself.
Budget max 2k

Would the graphics card be enough to still game at full resolution:
Nvidia GeForce GTX 1060

Thanks for your feedback.

To get the most out of this gaming monitor, you'll need at least a GTX 1080Ti, or even better an RTX 2080 for DLSS support in games (later), or preferably RTX 2080 Ti.

Integrated graphics will hardly manage it, but even the GTX 1050 can handle it according to Nvidia (max 7680x4320 @60Hz). It should also be possible to achieve 5120 × 3200 at 60 Hz with two DisplayPort connections (so two of these monitors if you need all-round vision ;)

Of course they don't write anything about the fps during gaming, but the monitor is roughly comparable to 4k. So a card that can handle 4k well won't have any problems with this monitor either :)
