Hello guys, i'm planning on building my first desktop, I am a 100% noob and was hoping for some help. A friend of mine bought an Intel DP67BGB3 and didn't use it so he sold it to me for a really good price. My question is about the Ram Memory, the specs say that I can use 1600MHz/1333MHz DDR3, but which one is better? 1600 or 1333? I plan on getting an i5-2500k. I also have a few other questions that I will get to later.
