Are you rocking a preview build of Windows 8? If so, you don't need to go without CPU-Z. There's a new update available, the first one in about five months, that brings CPU-Z up to version 1.59. Among the short list of changes is official support for Windows 8. The new build also recognizes Intel's Core i7 2960X, 3930K, and 3820 Sandy Bride-E processors.
Along with support for Sandy Bridge-E chips, CPU-Z v1.59 reads and recognizes Intel's X79 chipset. The update isn't all about Intel and Microsoft, however.
Other additions to CPU-Z's database include AMD Opteron and Valencia (Bulldozer), AMD SR56x0 I/O bridge and SP5100 southbridge (Maranello), and several VIA parts (Nano 1000/2000/3000, Eden X2, Nano X2/X3, and QuadCore).
