I have a Gigabyte GA-M55-SD3 Version 1 mobo. Have just bought a 9500 ($189 with free shipping from Newegg!!). My system is currently running a 6000+ but I use this system in a recording studio and I hoping Quad will be better for wave file processing. I also ordered an MSI 790x mobo but would like to send it back if the Phenom will drop into my current Mobo. Gigabyte support is worthless.....will it work in the SD3?? Thanks!
