I have just sprung big bucks for an Intel i9 with a Gigabyte x299 gaming 9 motherboard, 64 GB of 2666Mhz RAM, 2 Samsung 960 Pro 1 TB SSD's (in RAID 0, for a 2TB drive at twice the speed, and in M.2 slots, a newish higher speed bus), and an adequate graphics card (GTX 1050). It will be used for a DAW (digital audio workstation). 64GB of RAM is insane unless you work with high resolution audio (or video, especially). For example, one of my plugins is a piano which is 13GB in size, and needs to sit in RAM to lower latency. I have a lot of other plugins like strings, drums and other instruments which are all measured in GB's. Speed is of the essence; instantaneous is what you need but can't get. I can't report on it because it hasn't been built yet.
As for the present Ryzen CPU's, they aren't up to the i9 in some categories in tests that I have seen, but it looks like the upcoming Ryzens will be a better bang for the buck than the still-to-come i9's, the best of which will have 16 cores at the cost of $2000 U.S. I can say that the i9 seems to have overheating problems when overclocked and needs the best possible cooling system. My i9, the 7900 ($1000 U.S.), has 10 cores (20 threads) and 44 lanes, all of which contribute to it's speed and efficiency. I'm pretty much an Intel fan, I guess, but not fanatical about it. I did consider a Ryzen as they have made great strides recently in the CPU wars, and are almost certainly going to make a big dent in market share due to their lower prices for equivalent CPU's. However, I couldn't wait for what's in the pipeline. By the way, one of the reasons the i9 overheats is because they use thermal paste instead of solder, which is pretty pathetic in a $1000 CPU. Hopefully all the complaints about that will cause them to rethink that position for the future i9's.
Another interesting thing that I have discovered in my recent research is that all the workstation-capable motherboards are "Gaming" MB's, because the gamers vastly outnumber the workstation crowd, and some of them are willing to spend $3000 on 2 graphics cards alone so that they can play games at 4K resolution at superfast frame rates, or use 3 monitors and so on. The last time I bought a PC was about 5 years ago (a couple of i7's and 2 SSD's each). Since then, (and I don't know how it happened yet), all the higher end MB's are now all decked out in LED lighting, which includes RAM slots, the RAM itself, even a RAM fan that I bought, fans, and various other things. You can set up various light shows in multiple colours and patterns. I'm not a big fan of having all the lighting, but as I had no choice, I bought a case with 2 tempered glass sides (plastic gets scratched easily, and ends up looking cheap and blurred after awhile) so that I could see it. That makes it heavier, but I don't plan to move it, so what the hey. It's a Coolermaster Mastercase Maker 5t with some metallic red paint here and there, and a clever front that has a slope to it and an opening at the top to allow air in or out. It also slides to the front when you need access to the DVD/Bluray drive, or can be removed completely. The top can also be removed for better ventilation.
I'm looking forward to getting it running; it's a vast leap in capability's compared to my formerly excellent setup.
