i've recently acquired a 4060 ti for €300 from a seller that i've been told was reliable. after installing the gpu and updating the drivers to the latest recommended ones i've noticed odd lag spikes lasting several seconds when using blender, these did not happen when i used my previous gtx 1060 ti.
How can i go about diagnosing if it's a gpu or driver issue? any benchmarks or tools i should use?

i'm on linux mint 21.3 cinnamon.
