I just sold my old GTX 1050 Ti for $35, and it vastly outperforms Vega 11.
iGPUs are useful, they just aren't great value for budget gaming PCs (unless we're talking super-duper low budget, where a $50 used GPU is really going to break the bank). HTPC/NAS that's going to run Jackbox at 4K occasionally? Great use case for an R5 with an iGPU.
