Major potential regrets:
NEW consoles this year, probably November. the GPU's in the consoles are equivalent to radeon 5700/xt class graphics cards out now, will probably be ok for 4k resolutions. will also incorporate Ray Tracing functions. but then there's the whole have to re-buy compatible software issue.
New video cards this year: potential for Big Navi/ RDNA 2 /whenever Nvidia decides to release consumer versions of Ampere (They've announced the
https://www.anandtech.com/show/15801...-a100-products which is for the enterprise market.) to make the current high ends (2080ti) look like mid range cards (ie 2060 territory).
AMD Zen 3 / 4000 series processors released later this year. Limited compatibility for motherboards. (550/x570 chipset only) 1 way conversion for b450 boards.
if you want Intel there's the 14nm++ 10000 series processors, while they have increased core counts it's dubious if there is any significant gain in performance from 8000-9000 series processors.
on the bright side RAM prices for DDR4 have been pretty consistent so 16/32 gb configurations should be good. 16gb should be minimum as that's what ps5/xbox series will have.
TL: DR bad to buy now because fundamental shift in hardware comes later this year and buyers remorse will combine with FOMO to make a very bad time.
