Attention. There are 775 mobos that work with DDR2 and others with DDR3. The problem is that those that work with DDR3 need a special type of DDR3 (I think it's called "low density", but I'm not sure). Consequently, if you want to continue using your DDR3 memory, make sure it is compatible with the mobo that you are going to acquire.

Q9400 has 2.66 GHZ and Q9550 has 2.83 GHZ. A little diference.

Some people have bought very cheap cpu xeon socket 771, which have been adapted to work on a 775 socket. Do not take it as a recommendation. It's just information. The decision to use xeon in mobos 775 is from each one. On the web below you will have a lot of information in this regard. If you choose this way, read carefully what it says on the web. The only observation is that currently there is no need to physically modify neither the mobo nor the processor, as long as the vendors have already physically adapted the processors (you must ensure that this is the case).
