RE: Building a new Ryzen 7 rig

I've finally getting ready to build a new PC. The GPU of course has been the biggest hold up but I recently acquired a GTX 3060. Almost any modern PC has more computing power than I actually "need" but one of the things I like to do with them is run BOINC projects (and in the process mine Gridcoin though it isn't actually profitable or anything). I haven't pulled the trigger on the CPU yet but I am thinking of buying the 5700G instead of an X model. My thought process being that I'll get more total work done with the built in GPU than I will lose by having a slightly slower CPU. Plus it is cheaper.
