The board is a GA-8SR533 (rev 2.0).
At the moment, it has a Northwood 2.8ghz CPU, which according to the Gigabyte CPU Support list for this board, it doesnt support. Yet the thing runs and works fine.
It has a Geforce MX 440 8x 64mb AGP GPU, which shouldnt fit in the board, as it only supports 2x and 4x, but it does and it works fine too.
Basically, Im looking at upgrading both to the maximum the board can handle.
