Yes. Qwen 3 32B needs 19.8 GB at Q4_K_M and the NVIDIA GeForce RTX 3090 has 24 GB, leaving about 4.2 GB of headroom, at roughly 26 tok/s (estimated) with room for up to 8K of context.

Assumes a 4K-token context with an f16 KV cache. A longer window needs more; a quantized KV cache needs less. “Max context” is the largest window that still fits in 24 GB. Figures are estimates from parameter count, quantization and memory bandwidth — the analyzer lets you tune KV-cache quant and context.
Context costs VRAM too. At Q4_K_M on the NVIDIA GeForce RTX 3090: 8K 22.8 GB · 32K 29.2 GB ✗ · 125K 54.2 GB ✗. Past 32K it no longer fits 24 GB — a q8_0 KV cache buys roughly half of that back, which the calculator will price for you.
Nothing to change — run it at Q4_K_M. If you want more capability, check whether the next size up also fits.
