Is there anything like WHEA errors for overclocking video cards? I know if the driver crashes or you get a blue screen it usually means lower your clocks but is there anything else besides artifacting, driver crashing or blue screens that can show if the overclock is unstable?

Nope, if it runs stable for a while, it's good. Although with overclocking that does not mean it will STAY good.
