Well I have decided to build a new system but can not decide on a motherboard. Originally I was going to go with a MSI 6pn diamond, but it has no support for the Q9550 cpu I want to get.The MSI p7n diamond supports it but not too sure about the board. Is there any other boards I should check out. I would like the option of tri-sli eventually. I will be running sata everything. Not sure about onboard sound. I don't know if I want an add on sound card and that is why I was looking at the p6n diamond. Any suggestions would be apreciated.
