The question can not be answered properly if you are not telling as your requirements for the system, especially the sofware you like to run. And your budget of course.
But about the evga sr2 thing : forget about it, if you are not able to pick it up for a bargin (maybe 200 euros) and even then you have to consider double cooling costs, double ram costs, double cpu costs, double energy costs, psu costs and a mostly expensive case to fit in that evga htpx form factor. So i think this is far away from a budget build
For the numbers : a well 4,6ghz oc will be round about 30 percent slower than a ryzen 3600x in non avx related benchmarks (for example https://browser.geekbench.com/v4/cpu...eline=13604584
). (CPU is running with 4,6 allcore, no boost to 5ghz, nevermind about the geekbench reporting)
Cinebench R15 (its a non avx bench) :
about 1100 MC and 144 SC vs about 1600 MC and 200 SC
CB R20 (uses AVX but the avx gap is not that huge compared to other software, for example pi benchmarking or so)
MC about MC 2300 and 290 SC vs 3500 MC and 474 SC
