It looks solid. The retailer doesn't specify the memory, but I hopefully that is RDIMM (Registered ECC memory), which Threadripper now requires, and makes like 50perc. of the build price increase.
Threadrippers have become more expensive themselves, but the RDIMM memory is big part of it.
I believe the 32-core 7970X to be the sweetspot. All the cost that RDIMM + Motherboard eats up makes the 7960 quite poor value. If you're already spending 5K, might as well get the 32-core.
It's also the best performing one for daily tasks outside of pure rendering performance.
It's still worth it if it's the main PC for both work & rendering. But if you have rendering farm, I am not so sure anymore.
