Definitely not. Sapphire's Vapor-X cooler is an excellent performer. You wouldn't get much more from an aftermarket cooler.
That money would be better saved for a future GPU upgrade (like the R9-290
that Prestige Worldwide
suggested - or waiting for significantly-upgraded GPUs to arrive with TSMC's new manufacturing process next summer).
