Hi all! I am posting what might be an obvious answer to some people on here, however, I am wanting to update my desktop PC graphics card with an NVIDIA GeForce GTX1660 SUPER graphics card. But the issue is I am not sure if it will fit my existing PC/motherboard. The NVIDIA graphics card I am wanting to purchase fits a PCI-Express x16 interface however I am not sure if the interface in my PC is an Express x16 interface. I have attached an image of the PCI interface from my computer's motherboard to help. Any information & advice would be much apricated.
