I would love the DDR4 and the 8 core processor, but I won't be making a new build any time soon. I built my current dev machine in 2010:

Asus Rampage III Formula board

i7 980x (6 core, hyperthreaded, 3.4 Ghz)

24 GB G-Skill DDR3 1600, tripple channel

Dual 160 GB Intel SSDs in RAID 0

HD 5870 Eyefinity

I recently upgraded my monitors to 3x Samsung U590D's (28", 4k), so I also gave away my 5870 and replaced it with two R9 280x's.

I usually buy right around the knee of the price/performance curve, but in '10 I was burried in money so I bought the best parts I could find, and I've been thrilled with the box. In truth, anyupgrade now would be for vanity, as this does everything I could want.

I've been waiting a long time to upgrade. I'll be doing the whole 5960X with SLI 880 GTX and 32 GB DDR4 with three 512 GB SSDs in RAID 5. I have to wait until the 880 GTX comes out for the main purchases though as I don't have a desktop GPU. I'll pick up the CPU once I see the benchmarks. (There are leaked ones which indicate it's amazing and overclocks to 4 GHz easily).

I forget sometimes that there are gaps between Intel's general release schedule and their internal/partner release schedule. This stuff has been floating around for a while around here in the form of test-beds. Good stuff. For our purposes though there isn't much a difference between the previous haswell stuff and this stuff, except it benches higher on fine-grain parallel workloads, such as those using omp.

Most of what we use it for, besides benching, is running multi-process large volume compute jobs, which works just as well on fat multi-socket servers in a cluster as it does on a multi-core. So no, it's not going to make much of a difference to me. With regard to personal builds, I don't suspect I'll see that much of a difference between the older haswells and these.

Still waiting for something like Intel's Knights line to mature a bit to justify the inclusion in build rigs.

A bit too pricey for me, I'm still running an i7 3770k until the prices come down a bit as the difference doesn't justify paying over half my monthly salary for CPU/Mobo/RAM. Definitely upgrading my GTX580 soon though.

I'm already running dual SSDs on my end with i7-2600k and I have yet to experience any form of lag (the GeForce GTX 580 WAS a monster when it was released).

Corsair power supply, I'd avoid it actually. Mine surged and killed my two previous drives (one SSD and one HDD).

"I wanna know what lag is... I want you to shoowwww meeee"

Ordered the Asus X99 deluxe with the 5930k, and 32 GB RAM. Seems the faster RAM is still expensive and wasn't any available for shipping currently, so I got rather cheap 2133 mhz and will do with that for now and get 64 GB ~3Ghz once more vendors are available and prices drop. Already have 2 x 512GB Samsung 840 SSDs + a couple others.

Ordered a cheap PCI-express SSDs too.. that probably won't be of much use.. but gonna try and see if it can work with PCI passthrough in VirtualBox or VMWare to install a virtual machine on.

What do you put on the PCIe SSD (as opposed to on the SATA SSDs)? The OS?

Same thing I guess.. just another way of connecting it :) Never tried one before.. but I'm interested to see if the performance is better for virtualization than using a normal virtual disk.
