Thats a nice amount of cash.
Get a 2080 super (spending lots on out of box oc is dumb. get one with a good looking robust cooler that is cheap)
a ryzen 5 3600X (or wait for the rumoured xt coming in a few weeks/days)
any b550 board (coming out in 10 days)
a 750 watt high quality power supply (b or higher on the psu tier list)
a case you think looks good.
an nvme ssd since why not its like 20cad difference.
and spend whatever is left on a nice monitor and peripehrals.
you could also fancy for a nice looking watercooler, but the box cooler is just fine for stock operations with not oc.
You might want to go for a 500gb good ssd, then instead of a hard drive, a 1tb intel 660p ssd. its cheap and really bad (compared to other ssds) but its much better than a hard drive so if you want your steam library to be on an ssd too, thats the best way.
I would say go for a ryzen 7, but while its in your budget it would not make any difference to performance in gaming, so its most a waste.
