I have settled on a i7-3770 processor due to cost and the 4 cores with hyper threading for my media server. Obviously this is overkill for a media server, but I wanted to have the extra threads for the heavy video transcoding load, and a Xeon or Operton was not in the budget at this time.

I do understand the basic difference in the "K" processors vs the non-K processors with Intel. And I also know that most people will recommend the non-K processor for someone who is not overclocking.

Microcenter happens to sell the K version for $230 whereas the stock i7-3770 is $260 and the i7-3770S is $280

My question is basically 2 fold.... first, given the cost part of the equation is skewed slightly to the 3770K, is there a reason to go with the i7-3770 if I won't overclocking? Or is a stock i7-3770 a better option over the i7-3770K.

Since the i7 is faster than I need, is it just as easy to underclock the K series processor so I can get a similar Thermal Power as the "S" version of the processor without having to pay the extra cost?

Some consumer grade motherboards do actually support the Xeon processors, though be sure to check the website to be sure of compatibility. Another plus with the Xeon is they have low TDPs like the 3770s.

As for the 3770(k) decision, there is no reason to get the 3770 at that price. The 3770K is just an unlocked version (afaik) and that means that you could probably sell it in the future for more.


Underclocking the K series processor is quite easy and so is undervolting. I managed to get my 2550K down to 1.065v at stock clocks whereas the motherboard wanted to run it at about 1.25v so I imagine it used less power and was quite a nice bit cooler.

Doh! What's really funny is I was focused on LGA2011-based CPU's when I was pricing, I completely missed everything based on the LGA1055 chipset (for server CPU's).

That being said, the server-grade motherboards are still a bit higher in cost so it still might end up being more expensive, so I still would appreciate an answer to my original question though, but I have something else to think about now.

I ended up going with your first suggestion as a LGA1055 server based system answers my real problem, but your 2nd response answered my actual question, so I selected that as the answer
