What to install on SSD???

[jcenzano]

I just bought a new computer and I will have an SSD for the first time.

I would like to know what should I install on SSD in order to get the best performance. COD only, OS only, COD and OS???

The SSD is only 120GB so I have to plan ahead to get the best use I can of the SSD space.

I have also a 10000 rpm Western DIgital HDD and I don´t know if it is better to instal there the OS and COD on SSD.

thanks in advance for your tips
