I have an RTX 2080ti.

I still play in 1080p 60Hz, and the 2080 is plenty. But I'm looking to train some ML models, and the 11GB VRAM is limiting for that.

Thus, I plan to buy a new one. Also I don't want a ML only GPU since I don't want to maintain two GPUs.

Since I'm upgrading, I need to think of future compatibility. At some point I will move to at least 2k, although still I'm not bought into 4k as any perceivable benefit.

Given all these, I wanted to check with folks who have either card, should I consider 4090?
