I do not think they are going to drop anytime soon due to the 9800X3D availability being so very poor.

7800x3d is performing fantastically so far
Have it set to PBO -20 and the 64gb Kingston (Hynix) 6000 CL30 EXPO setting
Seems to be able to sustain just over 5ghz with a r23 score of 18,700
Not too burst your bubble, but have you tested those curves, im just coming towards the end of my testing, should be finished by Tuesday morning, but this is how mine ended up, some are not bothered, but id rather live without data corruption and random crashing, that negative 3 is the best core on that CCD, every ryzen CPU has it, and basically its considered as so tuned from AMD that they basically will do next to no curve, currently I boost to 5.9ghz on my frequency cores which im over the moon with.

The quick easy way is set them all to -10 in the bios except your 2 best cores, set those to 0, get hold of Ryzen SDT debug tool which allows for changing curves in windows, also get hold of ryzen master just to find out what you best core and 2nd best core is, to start with I ran AIDA64 SHA3 benchmark, just select 1 core in the options, it will test the first core, takes about 5 seconds to test it, you need to click that start button at least 20 times to 30 times, if it passes, set the curve for that core to -15 in ryzen SDT tools and apply and try again, keep going until it crashes, then you know roughly what that core can do, whilst the PC is rebooting, enter that figure into the bios for that core, once your back in windows start working on the 2nd core, leave the 2 best cores till last, but then work on your 2nd best core before the best core.
I then run core cycler, I set the configure file up to run Y-Cruncher-Old 00-x86, 3 mins per core and let that run for 10 passes, if you get any crashes then you can look in event viewer, core cycler now logs easy to check events, and see exactly which core crashed, then fine tune it, test again.
For final tests ive run loads, but ive yet to have any problem, you can probably leave it there, for me ive run Prime95 Small FFTs AVX2. AVX512 and SSE for 10 hours each, Y-Cruncher full suite for 10 hours and yet to run is OCCT stability certificate for however long it takes to run and prime95 blend, so i'll run one during the day whilst im at work tomorrow and one overnight tomorrow night.
I kind of follow skatternech's guide for curves, but I substitute whatever that shimano's tool is which I cant find for ADIA64 SHA3 test to find initial curves, he does steps of -5 where as I do steps of -2, just depends how much you want to fine tune it.
I only really run the Y-Cruncher full suite component tester and OCCT as im RAM and FCLK overclocking too.
