Looking for a New CPU, Motherboard and Case

This explains how Intel CPU's are made - Link
But, If you feel you don't want to read it just think this.
They run batch's and out of those 25% or so are throw out, the rest get binned and checked for speed. The high end yield CPU's are kept (i guess to make the factory run better, faster?) And the rest are sold in to groups. That's where you get the types of CPU's Xeon i7-i5-i3, It's not the company wants to make that many types, It's the return of the process of making CPU's.

So really all CPU's from Intel are the same just some or high yield so or low, Low being some things turned off like lanes,HT, Cores, ETC.

So lets say you wanted a i-4790K Most people would compare for i7's and i5, because they only know those series, I would look at the 1276 v3, Same chip just the Xeon has ECC ram support.

This next one is trick as everyone thinks the same on this but there is people who know better and state the facts.
Not all Xeon CPU's are locked, There seems to be 2 sides to what people call overclocking.
1st way is BLCK rise of some Xeon CPU's because they can't mess with the anything else
2nd way is overclocking the way you would on a i7.
The first way has very little return, like 105mz but on most times that's for 26XX series Xeon's and because they have many cores 105Mz on 8 cores adds up with 2 cpu's running.
The other way is making like Xeon 1650 and overclocking to 5gz, So you might have to google and the findings because people just think Xeon = Can't overclock, and it's false.

One thing to notes, now i'm not sure where you work but Intel has a program i think it's called Intel Edge reward, and if you work for a company that's on their list then you get Intel parts for very very cheap. I'm talking i7-5930K for $179.00 cheap.

Might want to look at that first because the winter deal will be coming up and i'm guessing you will see i7-6700k for $79.00 and they don't last long, Plus it's not like you just get to buy right away, you complete training videos on Intel products, Like Best Buy,Wal-Mart etc to help the person sell people intel stuff.

I'll see whats around but don't let people say you can't find good deals on PC parts or get that because i said too. I just updated my i7-4790k to a monster Dual 2011 E52670 64 ECC beast for $390.00, I don't even have a PC case yet ! just sits on the motherboard box, but works haha

But, i would guess you need fast single cores, like 4 to 8 core 5gz for games as they tend to be single apps.
