NVIDIA's new driver release tomorrow will provide a number of enhancements, including bridgeless SLi and support for the 6600LE. Widescreen under SLi is also fixed, as is the overbright video bug.
So, in the end, the new drivers, most likely 77.76, the last digit may change, will be out tomorrow, barring any last minute bugs. They won't bring massive frame rate improvements, but they do bring a new SLi mode and bridgeless SLi to the table. They should at the very least be very interesting for geeks to fiddle with, and with the upcoming 80.xx drivers should pick up the performance race again. Looks like these will be a lot of fun.
