The answer is no -- you will be fine, senior vice president of content and technology at NVIDIA, Tony Tamasi, explains on Reddit: "System performance is impacted by many factors and the impact varies between applications".

He continued: "The impact is typically less than a few percent going from a x16 PCIE 4.0 to x16 PCIE 3.0. CPU selection often has a larger impact on performance.We look forward to new platforms that can fully take advantage of Gen4 capabilities for potential performance increases".

If you thought you needed a new PSU, think again -- you should be fine says NVIDIA.
