I don't understand what you see here that is significant.
To me it says either (a) Intel Pentium 4 CPU or (b) Core2Duo CPU, which comes in dual-processor or quad-processor models I believe.
You say you have (a), a Pentium 4. So this should be fine. My own ASUS P5Q3 use of the HD4550 in WinXP Pro SP3 has a Core2Duo CPU with 2 processors.
But why would you think from the Gigabyte writeup that what you have is not acceptable? Looks fine to me.
