Is there a particular reason to go with the Tomahawk Max, any particular features you need there?
There are lower-end B450 boards which should work just fine, giving you additional budget towards the GPU which, if it’s a gaming rig, is where most of your performance is going to come from.
I would just like to future proof for any upgrades that I might need in a few years.
Is the Rx 5700 not good enough?
