Z390 is the chipset you're looking for. Does that budget include your cooling as well or do you already have an aftermarket cooler? Here is a shortlist.
Yep Z390 and for me personally a Gigabyte Aorus motherboard from the Pro and Elite which are fairly cost effective and have very strong VRM's with a 12 phase and you can go higher dependant on budget to the Gigabyte Aorus Ultra and Master which are the top end...
