i normally run every 2 years. i shoot a lot, and hunt a lot, so i really never go beyond 2. if my string is fraying really bad (from my primos bow sling), i'll replace it earlier. if my string/cables stretch a lot (normally not a problem with good strings) and tuning requires too much twisting, then i'll change them.
if you need new strings, check out 60x, vaportrail, they make good threads.
I'm with others here, every 2 years. I change out the cables every 3 to 4 years. Keeping them clean and waxed will increase there longevity.

I keep them waxed and don't consider changing either the cables or strings until it appears the bow is out of time; generally caused by a string or cable stretching.
