Wowsers... your post has made my reply box go all funky...

Anyway.

Keep : PSU, Case, Drives.

They can all be used for a different PC.

Sell the RAM, CPU, board and cooler.

I'm not sure why the formatting is so weird, is my ram no good?

Nothing wrong with the ram, if its just one stick then buy another same stick for dual channel. 3200 cl16 is okay for ryzen.

Sell the cpu and mobo or make a spare pc out of it, up to you.

Also in September a 3950x is rumoured to come out which is the full 16c 32t monster daddy Ryzen. If you want that you can wait a bit longer or just go for the 12c.

I feel like I'll just keep chasing dreams if I don't buy something soon, I was going to get a 2700 a while back and now the 3900x looks amazing, the 3950 will come out and I'll then there'll be an even better one rumoured ,😁
I've got 3 years out of my current system so I think I'm ready

You crunch images right, do you feel like an extra 33% cpu is worth it? About another two months away to see whats up, then nothing will show case till end of q1 2020.

Also gotta understand how Ryzen chips are divvied up. The 6core cpus have one 8core chiplet with two disabled due to whatever reason. 8core ones have the full 8 cores for the 3700-3800.

3900 has two chiplets with 6 cores each. 3950 will have two with all enabled. Up to you which one you want for the work you are doing.

Wouldn't it be significantly faster than my 6700k 12 cores vs 4 cores?

So would a 3700x at double the cores and threads. But you mentioned the 3900 which usually only the people after HEDT platforms consider, as its pretty much where Epyc and the Intel extreme CPUs start coming in.

Just mentioning that the 3900 is the cut down version of the 3950 and if you’re after hedt then waiting a month or so to see whats up might be better unless you want to splurge now.

Roger that, do you think the 3950 will similar in price? If I can get a good upgrade for $1300-1400 I'll be happy

Most productivity software will be 2+ to 3+ times faster on the AMD 3900 (vs 6700k).

See some benchmarks here ... Ryzen 9 3900X and Ryzen 7 3700X Review

Note: The 7700k is compared in the article. It is about the same speed as a 6700K. Perhaps 5% faster at most.

There are two cases where the AMD 3900 won't be a lot faster with productivity software.

- Some (mostly older) software will not be able to fully use the 12 cores of the AMD 3900.

- Also, some software makes use of the integrated Intel GPU for acceleration.

you can keep everything and just change the mobo and the CPU.

the 16GB 3200 RAM is fine. dual channel on intel doesn't benefit you if you're not gaming. have not seen any testing (dual channel) on Ryzen 3x00 however ....

might be worth adding a 2nd hand GTX 1070 - most image processing software use a GPU for when you tweak a pic and it renders it to the screen. if you do, make sure you set it to max performance for your software in Nvidia settings.

and yes the Ryzen 3900 will be much faster than the 6700. i have a 6700K and if i did any more lightroom i will get the 3900 but unfortunately i don't use it that much.

I think on top of being 2-3 times faster for rendering and exporting, it should allow me to do additional tasks at the same time (I hope) yesterday I was exporting 350 photos from Lightroom and the program was unresponsive

Batch processing of what? Using what software? You might spend a bunch of money and not get any speed-up if you don't think this through some more, and give us some more information.

The answer may be different for video encoding, photo editing with Lightroom, or batch processing image recognition using some kind of AI. You also might find a software limitation that means not matter what you throw at it, maybe it won't go much faster. You really need to see benchmarks for the software you use. It could be limited by the disk, the motherboard, or the whole string of hardware, so a 2X faster CPU might get you 5% practical gain.

I have to say though, a 6700 isn't that old, especially compared with my 2600K which is still adequate for me. Look at the 2600K, 6700K, and 3900X on CPUBenchmark. The single thread benchmark speed for those is 1900, 2350, and 2900, if you're software won't scale to many threads you might get a 23% speedup if it's CPU bound. On the other hand if it's completely CPU bound the CPUBenchmark score goes from 11K to 32K which is a pretty huge speed up.

Update: you've just said above, Lightroom. Let me think some more.

Here's a Photoshop benchmark for the Ryzen - it's not Lightroom, but it might be the best you find. I'll point out the Ryzen 3900X is about about 20% faster real world than the i5 9600K. I expect that you might reduce your export time by 25% if you spend a bunch of money on a new CPU / memory / motherboard. Yes you should be able to do exports while the batches are running with less of a slow-down, if you have enough RAM (16GB probably plenty) and a decent disk.

With Lightroom parallel batches can take advantage of a threaded CPU, but my reading suggests CPU frequency is the primary thing that helps faster exports.

You must be super high volume or needing a very fast turnaround time for this to be worthwhile for you. I found that when I was working as a professional photographer I just did my exports overnight or while I had dinner - even with the 2600K that was fine.
