Shailat,
Yes to the question about the Intel Seattle. As far as I know, they are not conducive to overclocking, but for a standard setup they are by reputation rock-solid. I almost got one but went for an Abit BE6-II because of the on-board Highpoint UDMA66 controller (the Seattle only has a UDMA33 IDE controller) -- and I regret it, because I subsequently learned that the Highpoint controller is problematic and -- well, I'm having problems and I'm fairly sure that it's the culprit.
The general consensus seems to be that any 440BX-based motherboard from a reputable manufacturer is the right way to go right now; avoid the 820 chipset models for the present.
One point that also was not clear before I made my purchase -- the architecture of these chipsets is such that most of the PCI slots are wired in such a way that they will share IRQs with certain on-board devices if you use them, which, depending on your requirements for peripherals, might cause you some consternation. For example, PCI slot #1 shares an IRQ with the AGP slot; whatever IRQ the BIOS assigns to the device in PCI slot #1 will be shared with whatever's in the AGP slot. Same with slot #4 and the on-board USB controller. If the board has an on-board UDMA controller, this will be in the mix to (on my Abit board, Slot #3 shares an IRQ with this device, and its bus-mastering signals share the bus-mastering signals in Slot #5 as well). Just be aware of this; it will be more or less an issue depending on what all you want to put into the box.
