I bought my last computer at Cheap Guys Computers and it included the SG-80 with the Pentium 4 already installed and after two years, the only problem we've had with it is a damaged HDD from my wife dropping the tower while it was running. My suggestion-Do it!

Okay your Processor is not supported by your System Board. I will take some time and look to see what would be a good upgrade, but it may take a few days.

This is an Intel link and, down the page a little, there is a compatabilty option you can pick. This will answer your compatabilty question. You can also enter your info in the browse for product support .

This is your board by the numbers you supplied:
http://www.newegg.com/Product/Product.aspx?Item=N82E16813131199
You have Via P4M900 and VT8237 chipsets and Realtek ALC662(sound)
This is Asus's link for your board:
http://www.asus.com/Motherboards/Intel_Socket_775/P5VD2VM_SE/#download
It's supported to Windows Vista so, it may or may not work with Windows 7.
You can try your sound here, if necessary:

and, this is Via's link:

It appears your board has the support for Windows 7, if that is what you are running so these should be all you need. Let me know if I can help you further.
