I used to use the bogomips number as a rough guide. Thing is, the new CPU has a lower bogomips number than my current CPU does. That doesn't seem right. So, I guess that number no longer means much. So, I went digging on the site you linked to. I found this but not sure what to make of it. https://openbenchmarking.org/vs/Processor/AMD+Ryzen+9+5900X+12-Core,AMD+FX-8350+Eight-Core Some tests, my CPU is faster. Most, the new one is faster. Some by quite a bit. It seems most things would improve but others may not. Am I reading that correctly? I'm trying to figure if I'd be better in the long run to buy that expensive CPU or pick one of the cheaper ones you mentioned. I started off with a 4 core on current rig and went to 8 core and slightly higher frequency. Money wise it was pretty painless. I could do that again with new rig. Once I pick a CPU, the rest will come easier. Mobos have to have the right socket, then it has only certain memory sticks that will fit etc etc etc. Thanks for any light you can shed on this. Googling just leads to a ton of confusion. What's true 6 months ago is wrong today. :/ It's hard to tell what still applies. Dale :-) :-)
