I wish there were no thing as NDA. The whole waiting game is awful. I bought some some of the items I need for my new build and still can't decided if I go AMD or stay with my 8700k? I could save £300 if I just stay on my 8700k. All I need left is a motherboard and a case. If I go AMD Ryzen 3000 I need the mobo,case and new chip. With all the news of high price x570 boards, don't know if it's worth buying a x470 instead which might not be upgradable in the future? There is no firm proof ryzen 4000 with work on x470? I just wish we knew now what the prices are going to be like.
Why upgrade an 8700k unless you really need a lot more multithreaded performance, single core performance will be in the same ball park if you have an OC on the chip.
The whole 'old tech', 'security' is no real risk to a home user and mostly pitch fork mentality.
When the IT department of the blue chip company I work for with a 20bn+ research program start turning hyper threading off it may be time to think again.
Right now they are handing out shiny I7 laptops like candy with affected chips onboard.
