Intel was showing off it's upcoming Quad Core Extreme Edition QX9770 at IDF Taiwan and it's got one up on the QX9650 which was shown at IDF in San Fransico, which we wrote about here.

This Penryn based part has a native clock speed of 3.2GHz and a bus speed of 1,600MHz and the one on display was overclocked using a cascade cooler which keept it between -85 to -100 degrees Celcius so it could be overclocked to 5.4GHz, although it had aparently hit 5.6GHz a day earlier.

Charles "Fugger" Wirth was back and did the overclocking this time around as well and the SuperPi world record now stands at 8.4 seconds, beating the old one by 0.1 seconds.

The Aquamark 3 world record was aparently also broken with a score of 281,000, but last time it appears he scored 292,840 so we're not so sure he read the scores right. Finally the Cinebench 10 world record was broken, but Charles forgot to mention how quickly it was rendered, but he did all three tests in 1min 43sec which is quite impressive.

The processor was in an X38 board with DDR3 memory and from what we could tell it had a GeForce 8800 Ultra graphics card.

Here's a picture of the cooling system
