Let me help you with your query.
It is important to mention that the support is provided in English only. The processor in mention, It is an old product Socket LGA775. The boards in the market with the socket are marked as End Of Interactive Support or discontinued.
I am afraid to say that a motherboard with the socket type LGA775 is really hard to get and the processor in mention is compatible with that socket type only meaning that if you are lucky you can get a board with this specification.
In regards the video card and the board you may get the compatibility between the card and the board depends on the computer manufacture since they sometimes set limitations on the units.
