I think both P45 and X48 boards are filler products with the impending release of Nehalem processors in Q4 of this year. As I understand it, these processors will boast integrated memory controllers (like their AMD equivalents) and thus motherboards will have to be redesigned to exclude this. Plus it's a new socket altogether. In terms of future-proofing, if there is such a thing in this business, both P45 and X48 are poor investments.

Hey, guys P45 and G45 uses a newer 65nm technology and a native (not by overclocking the bus) support for 1600 FSB. And will also have support for PCI-E 2.0.... G45 is suppose to be an updated G35 with many internal bug fixes and about 3 times the performance gain over it's predessor G35 ... Hence it would be an excellent choice for nettops. It's just the technology that has taken another step and ofcourse we warmly welcome it, and yeah, also expect a good price tag and not something priced out of the world like 790i SLis..........
Well, have a nice day.

I don't think P45 is a filler at all. Personally, I find it ridiculous that the P35 has a 16x/4x combination than the traditional 8x/8x modes supported by nvidia boards 2 generations back. P45 boards should do pretty well this coming summer because of that major feature.

At the same time, if it ends up more expensive than the X38s, then it would make it one very bad filler product.

Are there any P35 boards that dont run at 1600MHz? 400MHz on a P35 is fairly easy to achieve, this seems to me to be a "filler" product to fill their own pockets

Darren, having fsb1600 support is not about wether the old p35 chipset could readh fsb 1600 via overclocking or changing the dividers etc. Its about the motherbaord natively supporting the new 1600 fsb intel cpu's. You'll find 99.9% of all p35 chipset mobo's do not support the new intel 1600 fsb cpu's. 

Its the same as numerous 965 and 945 mobos dont support the 1333fsb intel cpu's, meaning if you plug these cpu's in they will NOT work.........
