here, ive highlighted all the areas that appear to be different from a 1.0 OR 1.1 board:

1. The area around the bottom left is totally different.
2. Just to the right of that, the use of surface mount caps instead of through hole.
3. MCP instead of MCPX
4. No eeprom
5. Different ICS chip (square)
6. Funny plug where GPU fan plug should be
7. extra cap near the video encoder
8. that plug by the CPU
