Considering an upgrade from your current rx 6600 to a graphics card in the 500-600€ range, you’re concerned that the Ryzen 5600 might create a bottleneck. While the 5600 is a capable processor, pairing it with higher-end GPUs could indeed limit performance in some scenarios. For optimal results with cards like the 9070, 9070 GRE, or 5060 Ti, upgrading to a Ryzen 5700X3D would better leverage their potential. This processor’s enhanced cache and performance characteristics would provide a more balanced system, ensuring you get the full value from your new graphics card investment.
