A Reddit user is looking for hardware recommendations to upgrade their existing dual NVIDIA GeForce RTX 3090 configuration. The goal is to achieve sufficient VRAM capacity, specifically 100-110GB or more, to run quantized versions of the DeepSeek V4 model.

The user has an ASUS X299 WS Pro motherboard, a 1600W power supply, and 128GB of RAM. They are considering adding one of the following pairs to their current setup rather than replacing it:

  • Two modified RTX 4090s with 48GB VRAM each
  • Two NVIDIA RTX A6000s
  • Two NVIDIA GeForce RTX 5090s

The user is asking for experiences with similar hybrid setups and advice on which option best meets their requirements.
