I will keep my Radeon VII at least for crunching big numbers (in case that might happen), which is 5700 not capable of... The low power consumption on lower resolutions with framecap was an unexpected bonus, because even in that case i expected 300+W.
To answer some discussion above:
For now my system seems to have buses wider than required (PCI-E, SSD, HBM, RAM), with power cascade much higher than required (on both GPU and CPU), using PSU which has 90% effectivity at 10% load so i kinda expect very smooth performance, low heat and low power consumption even when more CPUs or newer GPUs might provide more total performance.
Its not just about e-peen, but you have to justify things like superwide bus on HBMs of Vega. In my case the goal is to achieve lower GPU latency, and better concurrent writes into VRAM compared to standard GDDRs.
