I'm really looking forward to these new chips. For a long time we were exclusively buying Intel systems for our servers, but we started dipping our feet into the water with Zen, then went AMD-exclusive with Zen2, in part because the 2nd gen threadrippers were a great way to get cost-effective 256GB systems (very useful for VM hosts when your VMs are memory-hungry).
With Zen3 beating out Intel on single-threaded performance, it really does kill the last technical reason to buy Intel systems. I had some spare cash in my IRA back in November last year (had sold off a bunch of oil and gas stocks quite a while back, then never bothered to reinvest it since I don't tend to follow the stock market any more), so I ended up putting it all into AMD shares, which has worked out pretty well so far.
