Games may not need more cores, but if you want to stream at 5k 1080p60 and record gameplay at 4k60 a quad core can't do it.
I'm probably missing something, but shouldn't that be something your GPU is doing? That's a textbook fixed function accelerator task, and both AMD and NV have excellent video encode blocks. The CPU should not need to do heavy lifting here...

Not sure. DDR4-4000 should outrun the i7-5775c's l4 in read, write, and latency:

There must be something about the l4's position as a victim cache that makes it more valuable than fast system RAM. I'll be ******************ed what that might be though.

I think you were right the first time. These benchmarks which show the performance of DDR3 vs DDR4 on Skylake include a 5775C and a 4790K and indicate that a 6700K with 4ghz RAM would indeed surpass the 5775C's performance with DDR3 2400, considering how close it gets with DDR4 3200 CL16.

GPU encoding visual quality is worse than software encoding visual quality. That's why some people encode on the CPU.
