Check if upgrading to a PCIe 3.0 slot is beneficial for your RTX 3080.
Basic system details: CPU is Ryzen 5 3400G at 4.1 GHz (4 cores, 8 threads). GPU is PNY RTX 3080 with 12GB VRAM. Motherboard supports Gigabyte B450M. RAM installed is 48GB DDR4. RAM speed is 3200 MHz. During benchmark tests on 3dMark, PCI bandwidth was low at about 6.63 GB/s. This raised concerns about potential performance loss. I also have a 1TB NVMe M.2 SSD on the main slot, which might affect GPU placement. The GPU is in the top slot. Should I consider upgrading to a motherboard that supports PCI 4.0? Also, since I play games at 4K and want future-proofing, any suggestions would be appreciated. Thanks.
R5 5600 with a 3080, which would handle the workload well even at high resolutions like 4K and beyond. For 1080p, you'd likely need something around 5700X or 5800X3D.
