Look for gaming cards like NVIDIA RTX 4070 or AMD Radeon RX 7800XT or better to handle rendering simulator software and graphics. These exceed the minimum required specs and will keep you covered for a few years to come. If your goal is to play in very high definition - 2K or 4K, you might want to consider a more powerful GPU like Nvidia's RTX4080/ 4090 or the AMD 7900XTX.
