You will need to give us a bit more info. Is it 2nd gen or 3rd gen Intel CPU and the most important name and model of your mobo, after that we can tell you all you want to know.
Hi
The i7 i have bought, is an i7 quad core, 3770k - which i believe to be ivy bridge. The existing processor i have is an i3 cpu, which i think is sandy bridge. As for my mobo i am not 100% sure on it as i have forgot, all i know is that its fitting my 16gb of 1600mhz ram, and my i3, 3.3ghz cpu again socket 1155 currently... hope this is sufficient!
