Dual Graphics Card setup
Dual Graphics Card setup
You can configure both AMD and Nvidia dual graphics cards on a motherboard that has one PCIe 3.0 and another PCIe 2.0 slot.
If your motherboard includes a PLX chip, it supports SLI. If not, it won't work. Cf doesn't require one. However, both options offer little value. Games don't benefit much from them, and there are minimal performance improvements. Just keep it as-is.
