Yeah, like Patience says, it'd be easier with TWO Creative V2's.
Your best bet is to keep the Creative V2 you already have, and GRAB another Creative V2 from eBay to get a matched pair.
After this, get some cool looking heatsinks and some thermal epoxy and glue them to your Creative V2 pair.
You'll probably need a good fan for some air movement down the length of the cards too...
If you can manage all this, then you'll have some GREAT 3dfx memorabilia (I should know, as I ALREADY did ALL of this to my matched pair of Creative V2's and they work GREAT!) 8)
It's up to you really, but the 3dfx community is a nice place to be part of!
PEACE! 8)
