Check the figures

DeepSeek: DeepSeek V3's weights are larger than Radeon RX 7900 XTX's 24 GB on the whole ladder — Q2_K alone is about 257 GB. As a MoE model it can run with its experts offloaded to system RAM, but far slower than a card that fits, and this site will not quote a speed for that setup. Choose a smaller model, or a card (or several) that holds the weights.
