Z790 Hero not running GPU as PCIE X16 but instead So, I intend to build a sub $100 rig for light gaming I already have a GPU

pcie 8x slot Feturing with Gen4 riser cable, supports PCIE ,Compatible with RTX3090, RTX3080, RTX3070, RTX3060TI, RX6900XT, RX6800 See all features

It should be backward compatible, but you will see less performance than if you had it in a PCIe slot since it runs at PCIe x8 instead

pcie x1 slot function Apparently the cross-compatibility and quality are quite variable PCIe = gen3 seems easier than gen4, though, and for your needs it sounds

PCIe slots feature the same pin layout and thus are forwards and backward-compatible However, a PCIe card slotted into a PCIe slot will
