Is this indicative of future potential bottlenecks? Maybe but i wouldnt be so sure.
This is exactly what I expect. I have seen what happened to my friends with their GTX 970 when 3.5 GB of VRAM wasn’t enough anymore. Even though the cards were still rasterizing quickly enough they weren’t useful for certains games anymore. Therefore I recently make sure I go for enough VRAM to extend the useful service life of my cards.
And I’m not just talking about buying AMD, I actually do buy them. I first had the HD 5850 with 1GB, then got my friends HD 5870 also with 1GB (don’t remember if I used it in crossfire or just replaced), then two of my friends each sold me their HD 7850 with 2GB for cheap and I ran crossfire, then I bought a new R9 380 with 4GB when a game that was important to me at the time couldn’t deal with crossfire well, then I bought a used RX 580 with 8GB and finally the RX 6800 with 16 GB two years ago.
At some point I also bought a used GTX 960 because we were doing some CUDA stuff at University, but that was pretty late, when they weren’t current anymore, and it was only used in my Linux server.
