AlCu, or just Copper?

[hazmatt87]

I have the AlCu variety that they made for video cards, its a good design. Keeps my 6800 nice and cool. The all copper version woudve got me another few degrees, but its not that big of a deal on the video card. For a CPU HSF get the all copper one.

Well, went with the AlCu, based on the weight, and prob not THAT much difference in cooling. Easy to install. Dropped idle temps 5 degrees, and load temps 10 degrees, so I'm happy.

Thanks for everyones input.
