Actually it is one of the top boards out these days with the new 875 intel chipset. allthought for the price i would justy get a P4P800 -E deluxe and just enable the memory excel in BIOS and it acts just like like a P4C800. (Note: only works in ASUS mobo with bios of 1.010 or higher)
I cant remember what it is exactly called but it is under the memory timings part of the Bios it might be different there are two different names for it.
Now there are other mobo out now that have the 875 chipset ( the Abit IS-7 ) which is supposed to be pretty good too, but im not familar with that board.
Other wise as far as P4 motherboards are concerned its good.
