Intel Core i7-975 Extreme Edition Processor Review

The Test System

Before we look at the numbers, here is a brief glance at the test system that was used. All testing was done on a fresh install of Windows Vista Ultimate
64-bit. All benchmarks were completed on the desktop with no other
software programs running. All of the modules were run in dual channel
mode with a 120mm fan placed on top of them to keep them cool except
for the Core i7 system that was run in triple channel.
