UPDATE
Im sending the motherboard back in a few days for the following reasons.
1. It wont boot past 400 FSB.
Although this isn't really the motherboards fualt, but more the chipsets.
975 Chipsets were made for low stable FSB's. SO it would make sense to get a 975 Chipset with a CPU with a high multi like an E6700, X6800, Qx6700.
But the 965 Chipsets would suit an E6300, E6400, and even an E6600 better because they can obtain much higher FSB's.
Since I have a 9X multi on my e6600, 400 FSB gives me 3.6 GHz, and I cannot boot above 380.
BUT with say an E6700, This would be an excellent motherboard as the e6700 has a 10X multi so 380X10 = 3.8 GHz.
I might pick up the regular P5B Deluxe with WiFi.
Oh and about the WiFi. It is SO much better then my PCI card. My signal strength is about 87 percent where as on my PCI Lynksys it was around 50/60.
I'l see what I can do and if I break 400 FSB I'l let you know.
