I get confused. When i look in the ASUS page i see "support AM2+ CPU", however i don't actualy see written AMD Phenom X4 support. So how is it? If it supports AMD Phenom X4, then it's damn good SYSMB, coz i can stick 4 GB 1066 MHz RAM in it, but if not, then the 1066 MHz FSB is a waste, coz AMD Athlon 64 X2 CPU does not support 1066 FSB...
