The questions are:

1. If all the parts are compatible
2. If Onboard video is enough for 1080p monitor
3. And if the RAM memory will work on that motherboard from the start, I don't have any spare ram to boot the pc and change the settings in the bios, so I would like to put everything together, boot the pc up and then go to bios and change whatever I need for ram to work properly.

Thanks in advance.
