Is a rtx 2060 super with i7 6700k and 32gb ddr4 ram at about 2400hmz any good for this ?
The RTX 2060 super is a bit overkill for 1080p ultra (unless you are after super high frame rates).
Also I wouldn't go with the i7 6700K, it's an old cpu now on a dead platform. I would go with AMD and their AM4 platform as it's well supported and has lots of upgrade options.
An AMD B450 motherboard + Ryzen 5 3600 is probably the best value combo for gaming at the moment (and you have upgrade options all the way up to a 16core cpu on the same motherboard). Just make sure the motherboard you get is updated to support the new Ryzen 3000 series cpu's.
Graphics card wise, for 1080p ultra an RX580 is generally enough. The Geforce 1660 / 1660ti are also good options and a bit faster.
