Hopefully memory controllers have been improved with new Gen of CPUs and they improve memory training speed.
As you should know, memory training happens because the memory controller degrades and can no longer operate reliably at the current setting. Even if AMD improve their controller, it's still a losing battle with OC memory. Many such kits have very low SPD profiles, which is what you'll ultimately have to fall back on. OC memory is by far the main culprit when it comes to causing stability issues for custom builds.
Unless you're building a PC for the purpose of benchmarking, stick with quality memory with the highest JEDEC speed rated for your CPU, then all of these problems will go away.
Why not? I will do it myself, but probably year after the launch when I can sell my current 7600x and get 8600x/9600x with extra $50. The performance jump between 5600x and 7600x in SC and MC is >30% and the later is released 2 years later. I expect similar improvement with Zen5. What we can say about the the Alder Lake owners who upgrade from 12th to 14th gen to get less than 10% SC improvement.
Also when I resell the 8600x/9600x after few years It will have better value than 7600x, probably $25-30 so its almost free upgrade
So, you rely on selling your old CPU for $50 off when it's halfway through its warranty period? I don't know your local market, but it seems like a poor deal for the buyer to me.
For the same PC. The money is not wasted if it gives me psychological satisfaction.
And saves me accumulative 5ms on some tasks.
Sure, enjoy your PC
But wouldn't skipping a generation then give you even more satisfaction when you can actually notice the difference?
I often recommend keeping the old and relegate it to a "spare" system (or give it to a family member). Having two operational PCs is very handy, both when the primary have some issues, and when a friend comes over for a round of gaming, having an "OK" secondary PC can still pack a whole lot of fun. (Not to mention, if you ever do any kind of "work", you should always have some kind of spare.)
I don't know what the "kids" do these days, but back in the days, we hooked up computers and played through LAN. Unfortunately I rarely have time for that any more…
