Saying as you own the 3900X would you say it is worth waiting for it to be restocked or should I just pull the trigger on a 3800X? Gaming should be no real difference between the two processors, but real world how are content creation applications? Abode, rendering, video conversion, ect...? Do you think the 3900X is overkill for a semi-professional compared to the 3800X? If you had to do it all over again do you think the 3900X is a little overkill and the extra horse power isn't being utilized?
If the 3900X would have been released to keep up with demand I would already have one. I already have someone interested in my 2700X and am awaiting a new 3000 series processor to build that rig for him and to upgrade my existing system. Its getting very frustrating for me who would like to get my system updated and for my friend awaiting my current processor...
My experience has been the same as most other people here. I can't get anywhere with my 3900x at Stock, PBO, or Auto OC, when running a heavy multi threaded load. So I also both Manual OC, and Per CCX OC.
Also for reference, I was bad ass at manipulating PBO with my 2700x. I got that baby on Launch day, and by about 2 weeks after launch I had PBO running my chip at 4250 All Core for Heavy loads, boosting to 4350 for Quad Core Loads, and hitting 4400 for Dual, and 4450 For Single. I could get higher than that with Base Clock overclocking, but unfortunately my RAID, Sound, 10Gbe, and NVMe drives HATED Base Clock overclocking so I had to settle with a 100.2 BCLK, which was still a modest Bump. I also had (and still have) 2 Kits of Flare X 3200Mhz CL14 Memory, so 4x8GB Dimms total, and I was able to runn it at 3266Mhz CL14 No Problem.
I have tried for 3 days straight to get something close to the same Boost Behavior with the 3900x. Right now, Boost just seems to be BROKEN completely for All Core Loads on the 3900x. The Second the Tdie hits 65 to70c, with anywhere close to a 75% Load across all cores, your Clocks drop to 4100, 4150Mhz at BEST. I have tried every UEFI, I have tried using the in UEFI PBO Settings in Both Menus, I have tried using them in conjunction with Ryzen Master, I have even tried using my old favorite tool for the 2700x, Zen States. NOTHING works to hold Boost at 4200Mhz or higher, and often, especially when your all core load hits close to 80c, Your All Core is dropping down to 4000Mhz, so it really hurts with my all core Loads.
For this reason I have switched to both All Core and Per CCX overclocking and this has worked great!
Now in regards to your question. If all you are after is pure gaming performance, then the 1 CCD chips will do you great. In fact they seem to be able to hit higher All Core Boosts then we can (I mean as far as PB & PBO actually working for some of them). But if you want to leverage those extra cores, want some extra head room, and if you anticipate games starting to take advantage of the extra Cores, Threads, and Cache that the 2 CCD sku's offer, than I would highly recommend the 3900x. Despite its boost shortcoming, the thing is fun as hell to play with and has INCREDIBLE Power. If you can hold out long enough I would even say just wait for the 3950x. If you do, I will sell you my chip at a discount when I buy it! LOL!
But thats a decision only you can make. Regarding availability, I have now been able to get 4 of these chips for clients in a timely fashion and am pretty sure you could get one too. It involves having a lot of patience, putting aside about a 2 to 3 hour time period where you are constantly refreshing your browser, but its DEFINITELY possible to get one, I have the process down now, I actually bought one just yesterday, and it arrived today already, it just seems that more people are aware of this which is why they sell out so damn fast. If you really want one, I am sure I could help you get one.
