So I've decided to build my first computer. I've decided to go with the Phantom 410 case. I'm not sure if I want to get the Full Tower or the Mid-Tower version yet. Don't really see much of a difference besides the price and space. What I really need help in is deciding on a CPU and motherboard. I'd like to keep it Intel and Ivy Bridge. This computer that I'm building will replace my old desktop that has Windows XP Home Edition SP3 on it. I intend to run Ubuntu on the one I'm building. So can I ask the community to help guide me in my first build?
Let's start with choosing a CPU. I've been reading about 2nd Generation processors and 3rd Generation processors. I'm guessing that the 3rd Generation processors are the newest processors, and therefore, better? I've been looking at this Intel page for hours trying to make sense of it. I think I'm suffering from information overload at this point. Now, I'm not sure if I actually NEED i7, so I'm open to other suggestions (i5, i3) also.
I think I'll leave it at that for now. Thanks in advance to those who try to assist me. If this thread is in the wrong place, I apologize, and please move it to the correct category. Thank you.
