Replacing 10 Year Old Driver

I have a King Cobra LV4 driver, which I bought 10 years ago.

The driver is still fine, but i'm sure a new driver with today's tech could add a few yards to my game.

I have two questions which i'm hoping some could help me with:

01 - how many yards extra should I expect by changing to a new driver?

02 - are you aware of any website that would show and compare the distance between my driver (King Cobra LV4) and new drivers?

Thanks in advance for your help.
