So I am planning a new workstation/gaming build and want to pick up a powerful xeon for around $200 or so, and drop it into a x99 gaming mobo ( thinking about the Asus x99-a or deluxe). I have been looking at the 2670 v3 and the 2650 v4, and cant decide which would be better for me. I would benefit a bit from higher single core performance(I will be doing 3k [1080p surround] gaming with a gtx 1070). The main differences here are just the older 2670 v3 has a slightly higher core clock and boost clock, and the newer 2650 v4 has a smaller lithography processing node. Both same core count, both same L3 cache, very similar tdp. I also plan to BCLK overclock as high as i can get it on my water loop. The only thing putting me on the edge about the v4 is that the motherboard I will buy will be bought off ebay, and likely wont be up to the latest UEFI version, and may will require an update to work with the new xeons, correct? Do most high end x99 boards have q-flash plus so i can update that without a cpu? Thanks.

I was really interested in some point about an ES chip. My perspective was simple after some research. If i wanted to try an ES chip then I should already have a standard commercial cpu on my board. Since that wasn't possible, due to budgetary issues, i dropped the idea. Also the more I read the more i found out how it guys tend to treat those chips :D. Another thing is that the latest Broadwell-e es samples (e.x. 6800k) has received poor reviews when it comes to oc. Many blame it on the fact that the cpu reviewed are engineering samples. Who knows, right?

So if you want to experiment buy it 'on the side' and if you are lucky and everything works as supposed then sell the consumer cpu. I wouldn't buy it as a main or only cpu. That...

There is no big difference in core performance between v3 and v4. Actually it is pretty negligible. I'd would go with the 2670. Keep in mind that with a '200 $' what you are getting is not an actual Xeon but an engineering sample. If that is the case there are some things to consider. Besides the ethical stuff those chips tend to be really peculiar. They are often underclocked, many times for a good reason. There is no warranty and their overclocking ability is a lottery. Be very careful when checking their credentials. Another thing is that for the Xeon the turbo freq listed doesn't apply for all cores, meaning that in gaming scenarios those samples tend to suck.

Also if this build is for gaming, a 6700k is still your best option by far at this point. it would be much wiser to go for a better than the 970 if you want to fully utilize the triple surround setup.

Edit: if you are to go with an ES or QS buy the mobo first and if you can varify that it is working. With some mobos the cpu might not even post.

There is much controversy going around about ES chips, regarding the legality of them, and how they perform. Some people claim that they are cherry picked and are binned higher and others say that they are not a finished product that cannot perform as well as the retail version. I contacted the seller, to see infact if it really is a ES, as it doesnt state anywhere on the page, but i think it possibly could be a retail version, as companies who buy loads of these cpus are trying to sell them off. So you think it will perform wore if it is in fact an ES? I cant really complain about not having the highest binned chip at this price point, but as long as it will perform somewhat close to retail, and can bump up the BCLK to get it up to 3.5 or 3.7ghz or so, i am happy with that.
