I'm a big fan of the Fry's specials that include the ECS boards with VIA and nVidia chipsets because most of them are priced so they're giving away the boards at the current price of the chip, alone. It's a great way to set up a competent machine for office apps, but as others have said, they're pretty useless for o/c-ing.
If you want to o/c, the deals, themselves, are still good because you have a decent new board to sell to help pay for the one you need for that. You still have to do your homework about how far you can take a particular model. For good info about what you can do with your CPU, search for 2800 on the CPU/Processors and Overclocking Motherboards forums, here and on
