Well, first, I don't know that the 8800GTS uses 26a all by it's lonesome; I think that's a very liberal base eVGA recommends.
I myself have a 3x 12v rail system with a cumulative 38a, which isn't much more than yours and that single rail is better (less 'wasted' energy).

While uGuru is great, I don't know how much I would trust if for straight rail ratings; do you have a voltmeter? If so, measure your 12v line directly and see how it looks.

Also might want to consider updating the BIOS to the newest official at very least.
