I think this is just about a given, tbh. nVidia GPUs are going to benchmark like shit in 2025 with low VRAM totals now that we're at the point where the games needing more VRAM are actually out.
Although that's mostly going to be a thing for the mid-range (and low-end if they return to that market). For 4070+ GPUs VRAM is weirdly low, but doesn't seem to cause any problems yet (and honestly I don't see it being a problem until the next console gen).
I have 5 PCs and 8 monitors in my home and they are all using DP except one that's really old and uses DVI. DP is the standard connector for PC monitors.
