Personally, I do the old skool way... I know I don't have to but that's ok..
Very thin line of grease on the side and spread it out thin with a razor blade.
But the line down the middle seems to be good for some just as long as it is not way too much.
The small amount in the middle would work good for my i7 cuz it's a little convex.(Before I lapped the 3570)
hey thanks for all the help OnDborder! i'm stable at 3.8ghz...and i'm pretty happy
