Graphics card waterblock - copper or nickel?

[WNxDynam0hh]

Hello, I was thinking of watercooling my graphics card along with my CPU, but am unsure which to go for as the waterblock, copper or nickel;

I understand that copper has great heat dissipation, but am unsure of the nickel side to things (nickel will look better in my case)

I hope this might help you with your question

Copper is the better of the 2 choices. That is the "moral" of the other story (thread)!

are the nickel plated blocks plated on the inside channels as well or just the outside for looks? i could see a slight usefulness of the plating if it prevented copper oxidation in your loop.
