The P8Z77M-Pro is used with me in a computer the following configuration:
ASUS P8Z77-M Pro
Intel i5-3570K
Trancend 8GB Dual Chanel Kit (2 x 4 GB)
2 x Seagate Constallation ES 7200 500GB in RAID 1
And replacing a computer with this configuration:
ASUS P8H67-M Pro
Intel i5-2500K
Trancend 8GB Dual Chanel Kit (2 x 4 GB)
2 x Seagate Constallation ES 7200 500GB in RAID 1
Both systems can only be described as extremely stable and the installation does not constitute an obstacle. However, you can in daily operation an increase in performance, the course also depends on the processor used, talking. In any case, the board / processor combination is a worthy replacement for the old. Finally, since one also of "satisfaction factor" and is highly subjective.
A BUY recommendation, anyway.
