I see. I thought it was the E5 2640 V2 that was going for $19 each.. That would be some deal

I believe this refers to PCIe 2.0/5g bus limit with V1 CPUs on these Intel motherboards. V2 CPU gets you PCIe 3.0/8g bus.
That's not entirely true according to my understanding. AFAIK, there is a short whitelist of PCIe cards that will run at 3.0 speeds with a V1 CPU. They had to go through some extra validation or additional steps for that though.

Would love to pickup some E5-2660v2 CPUs for my current project, but would like to find a deal for under $100 on these...

I would love a pair of E5-2660V2 under $100 ea/$200 pair too! Will let you know if I run across any. Closest deal is best offer $120 ea from esisoinc on ebay right now.

@Stereodude Can you please share a link to said "whitelist"? I've looked briefly and find mention but no actual list.

I am running 2670v1. So this v2 is 400mhz slower, but 2 more cores. I think there is a lot of people on the cheap 2670. I would think we would pass unless we have boards that use pci gen3, and we really need gen 3. I keep looking for the magic v2 CPU upgrade, but for the same mhz and more cores, there is nothing cheap right now (and so many models to look for that it's actually confusing to keep a watch on). Anyone know what cpu model would be something to watch for (something sold in high quantity that we will see getting dumped in the next year).

So far it looks like the E5-2690 v2 has had the most movement downward in price for a high end E5 v2 getting to ~$400 each so far, but it's hard to say if it's just the first to fall or if it will be the E5 v2 with a glut of supply.

Edit: On my test x264 workload the E5-2690v2 is 38.6% faster than an E5-2670v1.

Has anyone actually bought these and replaced their 2670s? Wonder if there is any slowdown. I know it's 400 MHz less but 40 cores would be nice

With recent launch of AMD and Intel server CPUs, there should be hope bigger companies will upgrade their servers/CPUs and that it will bring more such v2 CPUs into the used market.
Paying $800 for a pair of such is IMO, too much.

i tend to agree. i can't see myself paying for the v2 CPU prices i've been seeing on eBay. The sellers apparently think they can ask for more and have raised prices recently too. I walked away from all that and just picked up 4 E5-2660v1 for $25 each. I was originally going for a E5-2660v2, but they went from $100-120 to now $130-140. For the price of one of those, I got 4x of the v1; that'll have to do until i see the v2 come down more.

damn, link to the listing/seller for e5-2660s? I've been trying to get 8 but sees no one wanted to budge lower than 34-38 or so.

i would, but it was a 'best offer' deal and honestly i didn't have a good experience with the seller so I wouldn't recommend. also, the seller no longer has them listed. $35-ish is what i seem to find too normally.

v3 and v4 are terrible for single threaded anyway. v2 2687w and v2 2667 v2 are the best cpus for mixed use and none of the v3 and v4 are as capable

I think that partially depends on whether your application makes use of the additional instructions that were added after the v2 CPUs. The Xeon E5-2689 v4 looks pretty potent to me.

2687W V3/V4 are as good as it gets for single threaded 10c/12c Xeon processors. However those command a high price premium. The 2687W V2 also commands a high price premium even for QS samples. Also the 2667 V3 is available but as an ES2.
nope. v3 and v4 are slower than v2. just marketing fooling you.

the ONLY v3 or v4 faster than a 2687w v2 is the 2689 v4

its terrible intel cant make a decent dual cpu workstation now. and with Ryzen the problem is worse. they are all going wider because they cant go faster. it sucks.

you cant buy a fast cpu with lots of ram. you have to go slow dual e5 and lots of ram or fast e3/i7 with limited ram. maybe noone cares, but its a potential hole in the market.
