ASUS Maximus II Formula - new P45 king?

[musasm]

Hello i have an interesting trouble with that motherboard.
I am now on stock speed, no overclocking. I can past any stress tests orthos, memtest, prime95 for hours. No problem but when i try to play games or 3dmark06 i would not survive more than a minute without promptly rebooting the entire system. I tried different Videocard, CPU, memory, PSU. The problem is exactly on either board or BIOS.
Look at these links, reviewers had the exact same problem:
