At the moment I am 50/50 on whether to build 3970X or 3990X. I am trying to have as little as necessary PCs and only the fastest so 3990X as workstation fits the bill (maybe even keep just super-fast workstation + cloud rendering as one smart person advised me :- ).
On other hand, 3970X is package without any hardware or system compromise. It's the ultimate chip (just like Xeon-3175X would be if it had normal power draw when clocked properly).
Also Juraj, I spoke to Optimus and they are aiming to ship out the Threadripper blocks next week.
Heh I just wrote them another email today but didn't get reply yet :- ). I really put a lot of faith into their product because the issue with cooling Zen architecture is not so much thermal dissipation but the transfer away from dies, so the block could really be a game changer.
Or not. Who knows..without any test, it's kind of risky to place 4000 Euro chip under new block that
'could' even potentially leak (through cracking or whatever, they do swear by their use of plastics).
Bit sad there is no TRX80, would have been interesting to see another potential behemoth motherboard like ROG DOMINUS.
