That sounds reasonable, but keep in mind that even a gtx1080ti can still struggle in 4k, which is why most professional gamers rather use the aforementioned 1080p high Hz designs.
make sure to post your configuration before buying it, to avoid mistakes. which store are you planning to buy from?
oh, and fuck matlab, i`m currently using it for my master thesis and oh boy, i`m quite a bit fed up ^^
I think I will be buying from a local store here in the Netherlands:

Will try to build my own system according to the following configuration:

but with a higher wattage PSU (750 watt), an extra 4 TB hdd and maybe a good high frequency 1080p gaming monitor from asus.
As the 8700K processor is currently in short supply (and expensive), maybe use the 7700K.
