Yep the 7820X seems to be the sweet spot (8 cores, 16 threads). Looks like it'll be about $830-$850 here in Aus. The 7900 is 10 core, not 18 core. Those higher core CPU's will have slower Single-threaded performance, which at least for the short term, it still important for gaming. My current PC is running a i5 3750K (2012), which has always annoyed me due to how mediocre it feels compared to my previous extreme Q9550 all the way back from 2008. It's well and truly time to upgrade this year.
The 7800X is $300 cheaper than the 7820X but
1) performs a fair bit worse in various benchmarks
2) doesn't seem to feature enough PCI-E lanes (particularly if M.2/PCI-E based storage takes off over next few years)
3) Is only a tad cheaper than the Ryzen 1800X CPU which is probably a better option around that price point.
