Currently 2x5070 TI + 1x5060 Ti. In doubt for next move.

Key Points

  • You currently run 2x 5070 Ti and 1x 5060 Ti with 48 GB VRAM, all on Blackwell.
  • The two upgrade options at the same price are adding an RTX 3090 or another 5060 Ti, with the RTX 3090 offering higher memory bandwidth and roughly 50% more VRAM.
  • Choosing the RTX 3090 would depart from a purely Blackwell setup, which could affect software optimizations and driver behavior while potentially boosting immediate throughput.
  • There is talk of very large throughput gains coming with future NVFP4 MoE models, which could influence whether to stay with Blackwell or invest in capacity now.
  • Practical factors such as power, cooling, space, and resale value should also factor into the decision.

Currently 48 GB VRAM. All Blackwell. My next move could be either:
- adding a RTX 3090
- adding another 5060 Ti
Both options are at the same price point. Adding the RTX 3090 seems a no brainer because 2x memory bandwidth and 50% more VRAM. BUT my setup wouldn't be any longer pure Blackwell and people seem to be hopeful about very large t/s gains coming with future NVFP4 MoE models.
What would you do?
