I’m looking for recommendations for a budget pairing for a 3700x left over from a previous upgrade.

The sole purpose of this build is to run 3x 1920x1080 monitors streaming instruments from a flight simulator at running 20-30 fps using a software package called air manager.

This build would not running any of the hardware intensive flight sims, however (that runs on an upgraded machine). Recs for new or used hardware are fine with me.

Thanks for your help -
