Upgrading...again

Well, I have a need. A need for upgrading. (pardon the bad parody)
Unfortuately, I have no idea what to upgrade.
I plan on getting some water cooling for the GPU's and some vapochill for the CPU on comp 1, but thats it. I ran out of things to upgrade.
I was wondering if you guys had any ideas.
One of my friends told me to try putting two audigy 4 pro cards in one PC and using 16 channels of audio. I'm not quite sure that will work nor would be really make anything sound better. Any ideas on this?
So, congo or gunnerman or anybody, any ideas on what to upgrade?
