A user seeks advice on investing $1200 for a second RTX 4080 to build a dual-GPU system for local AI inference and video diffusion during the 'Rampocalypse'. The motherboard's primary slot is PCIe 5.0 x16, while the secondary is PCIe 4.0 x8/x4 without bifurcation support. The user compares this to buying an RTX 5090 ($5000) or professional cards.
