A few degrees less for a few dollars less is how I would sum up Tuniq's TX-2 high performance thermal grease. It performed the best in all of the tests by a few degrees. A few degrees is significant to overclockers because we need to keep our temperatures down as low as possible to be able to overclock the furthest. Also, this TX-2 is a couple of dollars cheaper than Artic Cooling MX-2 and it performs better!
