IMHO, don't do it. The TDP isn't increased. Depending on the workload it will hardly be any faster than a 2670. I tried a E5-2689 v1 and found it was a big waste of money. With my x264 workload it runs about 3.05gHz vs. 3.0gHz for the 2670 on the 2nd pass. The first pass was about 10% faster where it would run at the full 3.3gHz vs. 3.0gHz.How about thesE: E5-2689 SR0L6 20MB 2.60GHz (MAX TURBO 3.60GHz) 8C LGA2011 - TESTED/WARRANTY | eBay

I just picked up a 2687W v2 for my single processor E5 v1 system to replace the E5-2689 v1. It wasn't 2670 v1 cheap, but good enough that I couldn't resist. It should be delivered today.Very good advise, thank you. 2670 is still a good deal in EU as well although the v2's are kicking in pricewise.
Just to follow up I went back and looked at my data as well as ran my new (to me) E5-2687W v2 CPU through the same test. The E5-2689 (v1) was 1.2% faster than the E5-2670 (v1) on the 2nd pass of my x264 encoding test. In contrast, the E5-2687W v2 was just over 25% faster than the E5-2670 (v1) in the second pass.Very good advise, thank you. 2670 is still a good deal in EU as well although the v2's are kicking in pricewise.
The base MHz increase of 800MHz should result in a ~25% time reduction.In contrast, the E5-2687W v2 was just over 25% faster than the E5-2670 (v1) in the second pass.
Why wouldn't they get down to $500? The flagship E5-2690 V1's are down to ~$250.V2 prices will likely decline later this year and into 2018 but as the E5-2690 V2 is the flagship of the 1ocore Xeon processors of the V2 lineup it is doubtful the price will decline that low.
I got a real 2687W V2 (not QS or ES) for under $700. The last auction for one on eBay sold for $575. Unfortunately, it was later the same day a different seller accepted my best offer for more than that.The 2687W V2 will also be a while before the prices come down for that. It's a nice 8 core Ivy Bridge-EP Xeon but at the current prices it's not that favorable or irresistible even though the QS is selling for $729 USD.
Regardless, I don't see how that means the E5-2690 V2 won't fall below $500. Both the E5-2687W and the E5-2690 V1 are under $500. They were all around $2k originally.Actually the flagship is the E5-2687W not the E5-2690 V1 although the 2690 original oem price is higher and prices haven't declined as rapidly as the 2690. The 2680 seems to be taking the 2670 price declines and the 2670 has rapidly picked back up in price.
There's a small boost from the larger L2 cache and IPC gains. The clock speed under load after Tubro is 3.6gHz vs. 3.0gHz, which is only 20%.The base MHz increase of 800MHz should result in a ~25% time reduction.
Thanks for sharing, because the data point indicates it is not (yet) time for me to migrate from the 2670v1 platform.
I understand the post to say, "my real world use" the 2670v1 is 3.0GHz in "turbo" and 2687w is 3.6GHz in "turbo." Nice data point.In contrast, the E5-2687W v2 was just over 25% faster than the E5-2670 (v1) in the second pass.

Yes, there's still TDP headroom on the 2687W v2 at that point, but Intel limited the boost to 200MHz when all the cores are loaded. There's not much TDP headroom on the 2670 v1 beyond the 400MHz Intel allowed, which is why the 2689 v1 isn't much faster despite being allowed 700MHz of Turbo vs. 400MHz from the same base clock.I understand the post to say, "my real world use" the 2670v1 is 3.0GHz in "turbo" and 2687w is 3.6GHz in "turbo." Nice data point.
The 2670v1 is good for a 400MHz bump, but the 2687w is good for a 200MHz bump over the base MHz, both under load.
Good. I'm sitting on a pair waiting on the MBs to come down in price but will sell them if I don't see that happening.Looks like these have gone back up somewhat substantially for a v1 chip, compared to how cheap they got.
Might want to check out some Dell R620s on ebay, I'm seeing some barebones for relatively cheap compared to how much they were lol.Good. I'm sitting on a pair waiting on the MBs to come down in price but will sell them if I don't see that happening.
That would be a very bad idea. The accessories for Dell servers are costly. It's always a best bet to buy a fully configured Dell server instead of buying it as parts. For instance, power supplies cost as much as $130 each (750W~1100W) used. Processors would be costing at-least $200 for a pair. Dell branded HDD or SSDs are way too overpriced even for used ones. By looking at the listing picture, even the PERC card is missing, so that would be $160 for a decent H710P. 1333Mhz DDR3 ram would cost around $12~$15 per 8GB stick. Additionally you might also want to consider getting rails and front bezel.Might want to check out some Dell R620s on ebay, I'm seeing some barebones for relatively cheap compared to how much they were lol.

These were selling for 299 just the other day. That's probably about as much as a competing SuperMicro board but as 24 DIMMs, flexible LOM, 10 SFF bays, a chassis, and what is arguably a better management engine if you get the DRAC enterprise.
