You probably wont be able to overclock the monitor that fast. The Nvidia control panel has overclocking for monitor frequency. Best thing to do I would look for a used 144Hz 1920x1080p ISP panel monitor.
Do you have a link to a product page? Quick google shows nothing.
Typically to hit 144hz the monitor actually needs to be rated for 144hz (or at least 120hz and some pre-packaged luck), and don't remember any CRTs getting that high. I remember some doing 85hz out of the box, maybe they can be pushed to 100hz with a nudge and a wink, but not 144.
