Why the fuck are you even considering buying an LGA 1156 CPU? That socket is now officially dead, because socket 1155 came out just several days ago. Horrible investment. Like I've been saying all along, the only Intel socket worth dumping money into is 1366. It still out-performs the new Sandy Bridge chips. Intel, innovation? Ha!

Now, unlike Intel sockets, AMD plans to keep AM3 around for a long time. Three years from now, you'll be able to install the newest AMD CPU with not more than a BIOS flash to your motherboard. You won't have to buy an entirely new system to get another CPU.
