just use common sense. I have never work with an i7 cpu so I can't tell you what the alignment marker is but usually there is a marker on the cpu and the cpu socket that give you the idea where the pin alignment should be. Also, if the cpu already come with heatsink grease on, be sure to remember to take the plastic off before install. Good luck.
I have already puchased my motherboard (Asus Sabertooth X58) and a processor (intel core i7). I have seen a short video on how to install the processor, but I have been told by friends to lets professional install the processor. Is it that difficult?
Also I have heard there is a better match for RAM by the type of Mother board you have?
