I have a m3n78-em motherboard and i just got ddr2 1066 ram for it that doesn't run at full potential because of cpu apparently which is a amd 6000 am2 so i need to upgrade to am2+ for it work wonder if my mobo would work with the new am3 phenom x4 II cpus

DDR2 1066 is supported by AM2+ CPU for one DIMM per channel only.
And this motherboard will only take AM2 and AM2+ and will support AM3 but you will have a degradation issue.

According to the ASUS site FAQ for the mobo

I plan to buy AM2+ CPU and DDR2 1066. I found on that forum that AM2+ CPU does not support more than one DDR2 1066 memory module per channel. Is this true?

Yes, due to AMD CPU limitation, DDR2 1066 memory module is supported by AM2+ CPU for one DIMM per channel only. Please keep this limitation in mind when you purchase your DDR2 1066 memory module.

Here's a list of what it can support (http://support.asus.com/cpusupport/cpusupport.aspx?SLanguage=en-us&model=M3N78-EM&product=1)

Not in the core speed to my knowledge just the FSB frequency and the support for DDR3 RAM :)
