Only ever used Arctic silver 5 or MX-2. Personally, Arctic silver for small things like CPU, MX-2 for larger things like GPU and ram on a VGA card. Purely down to getting 2-3x as much in a tube of MX-2 though. Can't say I've noticed a big enough difference in temps to worry about it. Get whichever is cheaper at the time imo.
