Ok, so 770 can support it. I know you need a board that can handle the power draw, so any AM3 board (and in theory any AM2+ board) that can handle the 125W will work with it. I thought the 770 boards would only do 65/95W CPUs so I wasn't sure if the 770 could do it.
PWM = Pulse Width Modulation, and is used to intermediate amounts of electrical power between fully on and fully off (i.e. controlling fan speed or light brightness)
TDP = Thermal Design Power, represents the maximum amount of power the cooling system in a computer is required to dissipate. So a 125W TDP CPU will need a cooling system capable of dissipating 125W of heat.
Also, because CPUs can get toasty, you need a board capable of handling the heat too - hence a TDP support list for CPUs.
Anyone else notice the BEEFY heatsinks on the new Asus 890fx boards. They are on the northbridge/cpu vrm. In the new TH article, they tested the Asrock 790fx ,same there,with a fan to boot. My point is, whats generating all the heat ? How are these older 70 dollar AM2+ boards with single phase power and no heat sinks on the VR going to handle the 6 core ? Certainly with NO overclocking. Maybe turbo boost , constantly changing states adds some heat ?
I'm specualting, I know they add heat sinks for show on the top end boards and these new AMD boards are now over the 150 dollar mark, but is it more than that to?
Thuban is fully supported on my $80 Gigabyte 780G motherboard I bought in O8, lol Asking if there are any boards below $100 is just silly.

As far as Windows XP using all the cores, any app that is written to utilize many cores will do so. I received my new computer last month (1090T), and after uninstalling clunky Win7 64, and putting WinXP 32 back on, it flies.
h264 encoding in handbrake uses all the cores, as I believe the encoder (x264) was written to do so, where as xvid encodes with the same or different programs do not utilize all the cores.
