Thank you all for the inputs! A few points:
@ BitMaster I could not find the Seasonic at 1200W, only 1000W (and more expensive than my current choice). Any pointers? The AXi is nice, but it's a full 100€ more (+40% compared to the HXi).
Looking at your signature, we seem to live close by, depending on what you mean with SW Germany. I'm around Munich. On the classic online shops, the 1080 Ti comes and goes, but it's never below 820-840 €. The 1080 is 600-650€. The 1070 Ti 550-600€, and the 1070 the same (!), although a couple of stores still sell for 50 less.
Mala tempura currunt for RAM and GPUs :(
@Johnny_Rico Your MoBo looks interesting (similar characteristics of my choice, if not for the integrated WiFi, which I need, as the bloody router is on the other side of the apartment; and I prefer built-in WiFi rather than having a PCI or a USB --God forbids!-- occupied for it).
As for the Intel security threat, I am not that concerned, and I strongly suspect the 8700K, when OC at its best potential, will stay ahead for some time even after the introduction of the Ryzen 2 (at least for what concerns DCS). Plus, the price of the 8700K has nicely 'dropped' during the last days in my shop of choice.
Out of curiosity: why do you say the Obsidian and mechanical HDDs do not match? Vibrations? I see you have two in your system. I am not planning for one, but just in case..
Last, the 3866Mhz RAM set goes for +20% the price of the 3200 set right now.. I am all for marginal gains, but this is quite a step, I am not so sure of the benefits. Perhaps you bought it sometime ago, with lower prices? Now the 3200 kit goes for 400€, the 3866 one goes for 480-500€, at least in here.
@smallberries: exactly! I will keep my monitor at the moment, and I also suspect that a 900 would do for the time being. As or the Ryzen.. well, yes, but there is always something new just behind the corner (don't I know it, I've been postponing this new rig for way too long :doh: ). And I think the 8700K will fight the good fight for a long time to come..
