[totally_hagard]

So i just bougbt an i7 3820 and im wondering which motherboards its compatible with? Im slightly confused because some websites say lga2011 and some say its compatible with socket lga1155. Also, can someone give me some names/links of some cheaper motherboards? Im also having trouble just finding any under $250 lol.
Thanks for reading.

X79 socket 2011. They haven't been in production for awhile so they are not easy to find, especially new.
