when I plug my monitor into my gpu, I get horrible sound and visual lag but when I plug my monitor into my mobo, everything works fine. also when I have my monitor hooked up to the gpu, the CPU and memory usage looks really unstable. Should I get a new gpu? Or is there a cheaper way to fix this?

Solution
What is the brand and model of your video card? Try uninstalling the nVidia drivers, run DDU to wipe them fully then re-run the driver setup.
