I just did a new one at 4600mhz and the pny cards 1202 ( 1306 boost ) / 1900... 32887 points.
Somehow Catzilla has some issues with GPU boost 2.0 since it just disappear when i bring more OC to the cards, will try later.
All the rest benchs and games has no problems with higher OC, must be something with catzilla itself.
