The ASUS P45 chipsets typically have a very long list
of compatible Intel CPUs, e.g. P5Q Premium:

The P5Q SE is a bit less expensive and it too
supports the D 930:

If you browse the ASUS website, look for the
link to "CPU Support" or "CPU Support List"
for any given motherboard.
The P45 chipset is very mature and very stable,
and you'll be able to upgrade that motherboard
down the road with any of a very large number
of more current Intel CPUs e.g. C2D, C2Q, etc.
Sometimes a newer Intel CPU can be run on an
older ASUS P45 chipset, by simply flashing
the latest BIOS.
The LGA775 socket has been fabulously successful
for Intel, and consequently there are a very large
number of compatible CPUs and motherboards to choose from.
