Pratical differnce b/w 925 and 915 chipsets

[onepostwonder]

What is the pratical differnce b/w 925 and 915(p) chipsets given that thanks to MOBO manufactures we can already run bus speedsas high as processors can go. Apart from the official support of high bus speeds and support for EE processors is there anything else?

The 915 can use either DDR or DDR2 memory, the 925 can only use DDR2.
