Greg is looking to upgrade his processors and he's noticing they aren't that much faster. Leo says that processors aren't. They've found that faster processors get hotter and more unstable. So they've added more cores and more L2 cache to make them appear faster. We're pretty much at the limits of single core speeds. So Greg is wondering whether he should wait for it to die or replace it? Leo says just wait for it to die and keep his data backed up.
