The best performer in the shortest space is going to be this 6.7" long GeForce GTX670
[Edit: Removed repetitive/unconstructive comments] If your budget it unlimited, the Asus GTX 670 Mini is going to be your best bet.
So far you've listed max lengths of 7.6", 9.5", and 11.4" Which is it? Obviously as you step up in length, more and more options present themselves. What's your budget?Here are some more cards that will fit inside that 7.6" max length.
Make sure you pay attention to where the power connector pops out (rear/side). That will add roughly an inch to the length or width of the card. Make sure this isn't going to cause any problems.
Quite a few cards are under 9.5" so I'll hold off on those recommendations until you clarify what the max length and max budget is.
