It's possible to get around a 7c or 9c performance change, but you'd have to switch from the worst possible TIM to the best possible TIM XD As that's unlikely to be the case, it's more common for a 5c difference.
As to the original posters statement: Indigo Extreme is currently the /best/ however; Coollaboratories Liquid Ultra is REALLY REALLY close in performance to around less than a degree. The only thing about LIquid Ultra is it's a LOT less consistant than Indigo Extreme. Due to the nature of indigo extreme it's almost identical in performance between mounts, and Coollaboratories Liquid Ultra varies a bit, but at best it can match IX in performance. Coollaboratories is also a LOT easier to apply than IX and quite a bit cheaper.
