I'd really try to squeeze another $60 and go 800 FSB -

Otherwise you might as well just save some bucks and get a Celeron-D. 533 FSB, same as that 2.8A. The D is NOT a bad processor.

EDIT -
The Sonata isn't really needed with a 478 board, you don't need the 24 pin PSU. You can get an Enlight and save 50 bucks.

The black one should be back in stock soon, same thing as that beige one.
