Definitely stick with the CPU and motherboard and upgrade the GPU, then upgrade to Zen 3 if you need to once it's out.I'm in a bit of quandary what to do, to be frank. I am going to wait for Big Navi regardless, but I have a 3600 on a B450 Tomahawk Max, and a 5700xt. Do I stick with the 3600 and upgrade the GPU, then wait for AM5 to give me a good path? Or do I wait for Zen 3, and hope the beta bios on the Max is good to allow Zen 3, but then be stuck for path due to AM5 coming? And of course, we don't know if PCIE4 will reap a benefit with these cards. My guess would be no, but I'm not 100% sure. The MAX is only pcie3
Bit of a quandary really. The 3600 and 5700xt is serving me well, but I always want that extra performance.
