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.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.

It's mostly HBAs and ConnectX3 cards.@Stereodude Can you please share a link to said "whitelist"? I've looked briefly and find mention but no actual list.

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.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).

Edit: On my test x264 workload the E5-2690v2 is 38.6% faster than an E5-2670v1.
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.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.
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 tend to agree. i can't see myself paying for the v2 CPU prices i've been seeing on eBay.

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.damn, link to the listing/seller for e5-2660s?

Well, I felt differently and was willing to pay it. I'm sure they'll be cheaper later, but I'm okay with that. I also wanted top end V2 CPUs, not just any ol' V2 CPU.Paying $800 for a pair of such is IMO, too much.
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.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
nope. v3 and v4 are slower than v2. just marketing fooling you.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.
the ONLY v3 or v4 faster than a 2687w v2 is the 2689 v4I 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.
