<\/span><\/h2>\nYes!<\/strong><\/p>\nAs long as you have physical\/mechanical slot compatibility, your newer PCI Express device should work on an older motherboard<\/strong> without much issue.<\/p>\nSome examples: Yes, a PCIe 4<\/strong>.0 x16 GPU will work in a PCIe 3<\/strong>.0 x16 slot. And a PCIe 3<\/strong>.0 x16 GPU will work in a PCIe 4<\/strong>.0 x16 slot. But, of course, you'll limit your bandwidth when installing a new GPU in an older-gen slot. More on if that'll impact performance at all below.<\/p>\nSo, physically<\/strong> the card will fit, and electrically<\/strong> it will run fine as long as your power supply is also up to snuff.<\/p>\nHowever, we shouldn\u2019t ignore the elephant in the room here: as the fastest expansion standard for every major generation of PC hardware in the past 20 years, there are going<\/em> to be some<\/strong> discrepancies caused by using a new card on an older board. Let\u2019s talk about them.<\/strong><\/p>\n<\/span>How Likely Are You To Be Bottlenecked By PCI Express?<\/span><\/h2>\n
