1060 6GB here. Figured the headroom would get me a couple extra years out of it. At this rate I’m wondering if the card is going to outlast the concept of owning graphics cards. Partly because, as you mention, maybe NVIDIA will stop selling them. Partly because, maybe APUs will get good enough…
About 3 years ago I got an RX 6750 XT with 12 GB of VRAM for $330 and I expect to be using that until either it dies or my computer's RAM dies and I don't have $10,000 to replace it. If only I'd maxed out all my DDR4 slots when DDR5 was the hot new thing and you could get it for cheap.
Strix Halo looks quite good. Hoping the stars will align, and my GPU will hold on long enough for the RAM famine to end and some Strix Halo successor to come out.
