You don't need a new machine unless you're running hardware that is incompatible with 10.7. As mentioned, you can still get by with 10.6.8, just the OS won't render previews for the CR2 files, i.e in the Finder or, I guess, with Apple's apps compatible with that vintage of OS.
But then, maybe a new machine will give you something that will better handle the larger file sizes...
