The GF110 is the new high-end GPU from NVIDIA based on a renewed Fermi architecture. Even if the chip has not been officially launched, reviews starts already to appear online !

In french:

It seems reviews are pretty good !
To sum-up, full speed FP16 texture filtering, Z-cull performances improved, architectural tweaks, 15-20% performance improvements over GTX480 in games, less power consumption, quieter, cooler.
According to techreport, an interesting subtle change is that the 16/48KB local storage partition can be configured by the driver for graphics contexts, while it was only configurable in compute on the GF100.

Congrats NVIDIA :-)
