I currently have a MCP61PM-HM or Nettle3-GL8E that I bought from best buy. I have a evga 9800 gtx vid card and a 600w power supply. I would like to upgrade the processor from the AMD quad 1.8 but am trying to find nice options. I've heard the 9600 has problems with vista 64. I'm currently running windows 7 64 bit. Any input is GREATLY appreciated. I know how to install the hardware just not how to match it up.
