Unfortunately, you're unlikely to find the latest NVIDIA RTX GPUs readily available at a Navy Exchange (NEX). NEX primarily focuses on providing everyday goods, apparel, electronics like TVs and laptops, and other general merchandise to military personnel and their families. While they might occasionally stock some entry-level graphics cards suitable for basic gaming or general computer use, high-demand, high-performance RTX GPUs are generally not part of their regular inventory. Your best bet for securing an RTX card is through major online retailers, dedicated computer hardware stores, or directly from NVIDIA's website (when available).
