Finally upgraded GFX card

[The Dong]

Stuck with ATI, because I'm used to the way it works for video on the 
TV. Stumped up for this (don't have it yet, soon):

My question, is music oriented (omg!¬)
OpenCL is one standard in GFX cards, but afaik it is possible to utilise 
the massive processing power (and it is massive) for audio or other 
tasks suited to these types of calculations.

Anyone know of some OpenCL audio plugins (reverb is the obvious one), or 
even sequencers, or any software whatsoever just for the sake of it?
(but not the games)
