Hi guys, I used to have an account here a few years ago but I forgot username/email

I'm planning to replace my CPU. Right now I have an i5-4460 with 4 x 3.4 GHz which is 13.6 GHz total and I want to at least double that. I'm looking at Ryzen 5 2600X (6 x 4.2 GHz + 10% extra for hyperthreading is around 28 GHz) or even Ryzen 7 2700X which clocks at around 38 GHz using this measure. I'm running stuff that parallelizes very well so don't bug me about this wonky benchmarking ;)

- The 2700X sells in Germany for only 340 €, and I'm surprised that it's almost 100€ cheaper than i7-9700K, and 2600X is even more cost effective. Is there a trick to this? Am I counting the turbo boost wrong?
- Suggestions about MOBO? I've got an M.2 and six HDDs so I'll need lots of connectors and a PS/2 in case of USB problems (Win 7).
- Take 1x16GB or 2x8GB RAM, what works better with Ryzen? I don't really know anything about DDR4
- My PSU is be quiet Straight Power 10 400W, several years old, should I upgrade?

Welcome to SPCR...and I'm not going to touch whatever you are doing mixing cores and GHz. :) However, I suggest you look at some benchmarking sites to get a better idea of how the processors compare for tasks similar to yours. Anandtech's Bench is a good start.

Your PSU is fine.

Thanks for the link, it seems i7 is faster at some of the things but my stuff makes decent use of hyperhtreading when not at capacity, and I think I'd probably need a new PSU for i7, so I'm going with Ryzen.

What about this motherboard: ASRock X470 Master SLI https://asrock.com/MB/AMD/X470%20Master%20SLIac/index.asp, is it cost effective? I think it supports everything I have and it has Windows 7 drivers too :)

Can you suggest RAM for Ryzen 5 2600X or 7 2700X? Some sites say I need DDR4-2933, I'm not sure if that means 2933 and faster or 2933 and slower. Should I spend money on RAM with a heatspreader? RAM looks pretty expensive ATM
