I'm planning to get a Scythe Mine, I want to know whether or not I should get Arctic Silver with it or used the supplied stuff. I plan to overclock past 2.6GHZ on an X2 3800+. Does this stuff ever go bad? If it doesn't I might just buy 12gram container instead of a 3.5gram container and spread it on my current video card and video cards to come. What do you think? Thanks.
