Also getting at least 128GB DDR5 RAM for now. My requirements: * Up to 100B MOE models (GPT-OSS-120B, GLM-4.5-Air @ Q4, Qwen3-Next-80B-A3B) * Up to 70B Dense models (Llama 70B @ Q4) * Daily driver models - Qwen3-30B models, Qwen3-32B, Gemma3-27B, Mistral series, Phi 4, Seed-OSS-36B, GPT-OSS-20B, Nemotron series, etc., * Agentic Coding * Writing * Image, Audio, Video generations using Image, Audio, Video, Multimodal models (Flux, Wan, Qwen, etc.,) with ComfyUI & other tools Hope 48GB VRAM is enough for above stuff. So any cons with that card? Please let me know. Thanks. ^(I know that some of you would suggest me to get 4X 3090 or similar ones instead. But in my location(India), all the old cards' prices are in decoy range only(70-80% of new cards' prices, here most sellers won't reduce prices of old cards. Some poor gamers foolishly getting trapped on this) so we're going with new cards(My friend don't want to stack old cards, we're planning to get 96GB piece later after price down(?!)).)
