It's been 5 years - time to build a new PC!

why not build another AMD system like the 2700X cpu but that system looks pretty nice but a few reviews on the motherboard are NOT too good on that one (check newegg) I would not get that one personally.. I would get one that is rated better.

It looks very nice to me, why 2 x 250G SSDs? wouldn't a single 500G be more convenient ? and if you are planning to RAID them it doesn't generally gain anything. Also the Hyper 212 evo is good enough at stock or for a mild overclock but you'd need something better to really push the CPU

Other than that I guess the main question is whether a Ryzen 2700X build is a better choice or not, less Gaming performance by a small margin and a lot more multi tasking power. But it's also a newer platform and not all software has caught up to take advantage yet so you don't always see the difference in real world tests.

If you want a rig that can perform workstation task and game then you really should look at AMD. The 8700k is the best CPU for gaming, but the 2700x is within 5-10% and will be much better at work station task such as video editing.

I made a few changes, instead of running 2 850 EVOs, I would go with one 500gb 970 EVO. You also don't need a 750 watt PSU as a 650 watt will be more than enough. You really should buy RAM in kits as they are tested to work together. And for a dual channel system I recommend going with 2 sticks instead of 4 as it will put less stress on the memory controller. So I would get a kit with 2x16gb sticks of RAM. Even if it cost an extra $20. It will be worth it.

I also threw in a Phanteks case because I really like them. Fractal Design also makes some really good cases as well. I am not a big fan of cooler master, but that is just me.

Good luck and my condolences about your mother.

If you are video editing, Ryzen or even Threadripper make more sense. i7-8700k is all about single core performance, so good for games. Evo 212 would probably struggle a bit with the 8700k. Probably want something like a 140mm+ fan with a larger radiator. Cryorig R1 Ultimate, Noctua D15, BeQuiet Dark Rock Pro 3 or 4, etc.

You should see if you can find a 4x8GB memory kit rather than two 2x8GB kits. Don't want any instability from a non-matched set.

I messed with it a little, particularly in the storage. No reason not to get an NVMe drive at least for the boot drive. And paying $100 for older 850 Evo when you can get 860 and 960 evo in the same capacity for less seems a bit off.

But if you want a 12 core+ CPU for not a whole lot more and quad channel memory (not just 4 sticks in dual channel) there is Threadripper. Or there is X299 with Intel for 8+ cores (up to 18 cores at the moment, but that gets pricey. 10-cores is the middle ground.

Really depends on your primary goal for the machine. 8700k is decent due to its core speed, but it sounds like many of your tasks won't rely on that. And if you are going for high resolution gaming GTX1080 and up, then CPU performance isn't all that critical since the GPU becomes the limiting factor.

+1 to the 2x16GB sticks. I always forget that is an option since most builds really only need 16GB.

Swap the MX500 for a M2 version here:

You wil have a 64 simultaneous command bus instead of sequential queue. It makes non-CPU access speed and many-multicore performance much faster and is the same price.

There's a lot of considerations that need to be made with going Threadripper, as it's not as flat out 'better' as the paperwork suggests. Remember that your old 4Ghz 8 Core had rather bad IPC and rather worse power consumption; you'd have seen better performance in most apps with a stock 3750K and that was released in 2012 as the 8350 needed the extra cores to keep up and that makes it what we refer to as a 'broad design'. Even though 4Ghz is fast, its not doing as much work per core as modern desktop processors.

Single core performance is really important to the lifetime of your CPU (before you start to notice sluggish everyday use). You're not replacing this computer because it lacks cores, you're replacing it because you want something faster. 8 cores running at better IPC/clock will benefit you more 99% of the time, and will for at least the next decade unless you 4 screen multitask. This is true as well for Content creators, as UI performance suffers greatly and you already have a pretty broad render PC should you want one. You already have a broad core and it only lasted you 5 years so ignore those talking about future multicore: so many tasks simply cannot be made parallel.

The main reason I wouldn't go TR or Ryzen for audio production (as opposed to video production) is it creates input lag at the driver level when run at full performance, and clocks rather badly over 4ghz... hence the Ryzen Game Master app which disables sections of the wafer with high latency connections and effectively turns off 3/4 of the cores to eliminate that latency. The cost balance is your ballpark, but the fact you can't really overclock it beyond 4Ghz (due to the sheer number of heat sources) is a game breaker for me when combined with that.

Your DAW and ASIO latency HAS to run higher as a result simply to account for the CPU throughput lag. Real life effect is that you get less plugins/FX loaded for any given latency compared to an equally performing Intel chip before pops and overloads.

This is gamebreakinig for recording, but generally results are good beyond that.

Going down to a 4 core is not the greatest solution to anything, but it's only at that point that input lag becomes comparable to Intel; this is what the Game Mode of Ryzen Game Master does to TR.

Even though IPC is basically comparable between Intel and AMD now, Intel still can clock up to 5Ghz on most builds. That makes a 6 core 8700k OC compete with a 12 Core 1900X better than your 8350 competed with a 3570k and better in many circumstances, and a 7900X basically king of the DAW provided you can push it.

Oh, and you want a bigger PSU for that build. Your CPU alone is 180W. I would recommend 700W minimum as your caps will degrade in 2-3 years and bring the total power available to the system down. 550W is from the wall socket, not to the PC, so 80 rated 550W is 440W for your components.

That isn't how PSUs are measured. Wattage output, not input. At 80% efficiency that means 550W output, 687.5W input. Though I agree a threadripper build requires more power. Both Threadripper and the I9 can exceed their TDP via boost/XFR. So you want about 300W dedicated the CPU alone. Particularly if you plan on overclocking.

That article is pretty good at detailing Threadrippers issues when it comes to audio work. I think they worked to solve that a little in gen 2. I know the latency issues are reduced on the new 2000 series chips, so that might be worth waiting for. (And it gives you a chance to save some money up for more memory for the Intel build)

I don't know much about the audio production of Ryzen and ThreadRipper. I have seen many times over that yes Intel can overclock higher, but for rendering and situations where your video production apps can take advantage of the cores of threadripper, it is completely worth it. Now for gaming, threadripper is behind intel even down to something like an i5 8600k i think. A 1950x will completely destroy an i7 8700k in applications that can use all 32 threads. Also Threadripper has something like twice the PCIe lanes that intel has (unless you move to something like an i9-7XXX which costs a ton more).

Don't know if it would be worthwhile cause from what I remember, the Q3 release date is just rumour...

If you are willing to wait though, i'm sure it will be quite nice while also causing the current gen threadripper to drop in price more.

They pretty much announced it at Computex, at least to their suppliers. Q3 2018, so it would be shame it they missed it.

But the key there is that they are talking of 32 core chips. I assume they will refresh the line-up though with the Ryzen+ improvements.

So 8, 12, 16, 24, and 32 cores at least. Not sure if they will do any in-betweens. The only downside I saw on the block diagram is that two CCX would not have direct access to the PCIe lanes, they will have to go through the infinity fabric to the CCXs that are hooked up direct.

Also 64 PCIe lanes is cool, but I can't think of a case where your average consumer or even prosumer would need that many. Piles and piles of PCIe SSDs? Raid controllers and network cards? Maybe some specialized audio cards or video capture. But really that all adds up and most can be done in software these days.

I have a 1950x and it is an impressive CPU. It is amazing how fast it can complete a lot of task. There are a couple of things I would recommend though.

RAM compatibility is an issue. Make sure whatever RAM you get is what is on the motherboard QVL. If it is not on the QVL, then don't get the RAM. You should also get 3200mhz speed RAM. Ryzen CPUs scale very well with high speed RAM.

I would not go with the Corsair H100i. Enermax makes a AIO that is designed for Threadripper's massive IHS. It will provide much better cooling than the standard Asetek coolers on the other AIOs. TR4 is hot, so if you want to overclock, you should get a good cooler.

The 2nd gen Threadripper should improve memory compatibility and have a similar bump in clock speed. Ryzen cores scale almost 1:1. So for multithreaded task look for 2nd generation 16 core TR to double the 2700x performance. 2nd generation TR4 is supposed to release in Q3. Threadripper was first released last August, so I would expect a similar timeframe.

I wouldn't get a rosewill PSU but everything else looks good.
Seasonic FOCUS Plus Series SSR-750FX 750W 80+ Gold ATX12V & EPS12V Full Modular 120mm FDB Fan Compact 140 mm Size Power Supply $95 on Newegg. Seasonic makes a really good PSU.
