Firing Squad recently updated their article about GeForce FX performance with the Half Life 2 engine:

and in almost all cases, the 5950 has lower performance than even the ATI 9600 Pro! I'm quite surprised by this since the FX is superior both in theory and practice...
What could explain this besides perhaps the issue of using a full-precision floating point format?
