Not to rain on anyone's parade, but all this does is add support for high end Thoroughbreds.
Unless you're gonna run them, there really isn't a need to upgrade (esp. if the rig runs fine as is...don't fix what ain't broke).
Now if this added some more FSB settings (particularly 141, 142, 143...LOL), I'd be on it like white on rice.
Right now my duallie is running a pair of XP1600+'s at 12.5 x 140, and I could hang Chevrolet emblems all over it, 'cause it's "Like a Rock".
