Stock Cooling or Zalman VF700-ALCU?

[Arbb]

I have a Leadtech A400 GT (6800 Gt) modded with the 6800 ultra Bios, runs fine but temps seem a bit high aprox: 65 idle and 75 under load running with the stock cooler. I can get a Zalman VF700-ALCU at no cost but is it worth my while to change the HS as the A400 seems to already have a decent heatsink on it?
I would like to squeaze as much out of this card before upgrading to PCIE!!

Is it worth your time? Is it worth my time to answer your question?
Just do it.
