I just bought this card, I like it though it is way to loud. little matter though I was planning on buying a block or it anyway. what is better nickle or copper?

nickle is but a finishing touch to a heatsink, right? :)

so nickle is better for heat absorption and it looks better? I think i'll go with the nickle then. The block is already 150 USD anyway if not getting copper costs 20 dollars less what does it matter. :)

It is not solid nickel, likely copper is underneath. Nickel plating is done purely for cosmetic reasons...

yeah that seems reasonable. I was thinking about the specific heat properties of each, and I haven't bother to check but I'm guessing that copper is better at absorbing heat easier but as you mention nickel does look pretty bad *** haha.
