new computer configuration

[bluesnow]

Hi everyone!
Last time I build a computer I was on pro tools 7.4
Now i'd like to move on with reaper...

It got old and was about to buy a new config. As I am quit uncertain about building my own rig, I'd love to have your feedback on my first thoughts.

intel core i9-9900k (lga 1151, 3.60 GHz, 8 core)

4x 16 Go, DDR4, 2666, DIMM 288

mother board: Gigabyte z390 designare (LGA 1151, intel z390, atx)
(I need thunderbolt because I d like to have an apollo x6 as a sound card)

carte graphique: ge force gtx 1650 (4 go) I'd like to have 3 monitors at least

windows 10

well, hope you'll find my config interesting.
thanks in advance for any inputs.

best
