Wow, it's been 3 weeks and still no 1900x reviews. I have been a bit tempted to save money with it, as with most of my use all the PCI lanes will be biggest benefit - two video cards at x16 and the tertiary card still at x8, and still all the lanes for M2 storage. There's a little trade off, as a few apps I use the most rely more on core speed, then a few others used less often will use most or all the cores.
Anyone running a 1900x, or 1920x vs the 1950x? Word when they came out is the first two should be more overclockable with less cores pumping out heat. Of course, if the difference isn't much, it's very tempting to just get the 1950x and have a beast.
All three of them are incredibly close to the process limitation of ryzen. Therefore all overclock as well as the next. It seems all three generally clock up to 4.1GHz with a higher number of them hitting 4.2 than the 1800x did before.
