I would recommend against going with a capacitor you just happened to find that looks like it has the same voltage/capacitance specifications as the stock Novak capacitor.
There's a spec that is not rated on the capacitor that is called ESR which has to do with the capacitor's ability to cycle between charge and discharge.
I would simply recommend picking up a #5679 Transcap Module for your GTX:
