Requirement:
Upgrade existing 4770K to more modern CPU, faster SSD and RAM. Ability to overclock to 4.5Ghz+ with ease.

Usage:
Database processing PC. No gaming or graphics (existing HD 5670 to be used).

Budget:
£850

Current Spec:
4770K (O/Cd to 4.7Ghz)
Hydro 80
Z87-HD3
Avexir Venom Series 8GB (2x4GB) DDR3 PC3-17200C9 2133MHz
250Gb 840 Evo

This rig is coming up to 2 years old. I appreciate it is still a decent performer but I could do with DDR4 and / or quad channel memory. The reason for this is that the PC is used to number crunch databases that are held in a ramdrive.

The SSD would either be PCIe or M.2 but would need to be the type that hits 2000Mb/s+ Read, 1000Mb/s+ Write

Parts List:
O/C CPU
Water Cooler
Motherboard
RAM either 2x 4Gb, 4x 2Gb, 4x 4Gb
SSD 250Gb PCIe or M2
PSU quiet, high efficiency
 
Do the tasks your performing benefit from extra cores/threads? If so X99 would be a better choice. On the mainstream range a 6700k will net a higher oc and increased ipc due to the newer architecture. But your still stuck with 4 cores and 8 threads. Also, with X99 you will probably max out around 4.5ghz when overclocking unless you get a golden chip.
 
It's going to be single threaded processes so a higher clock, rather than multi cores is essential.

No point in raiding because most of the processing takes place in RAM.

Current Bandwidth is around 20GB/s whereas DDR4-3200 should be 30GB/s. Quad channel should be 40-50GB/s ?
 
after reading this again. and seeing you only want DDR4 and a very fast single core.???

My basket at Overclockers UK:

Total: £444.47
(includes shipping: £10.50)

Overclock the I3 and right now nothing as better single core performance that an skylake cpu.

X99 looks to be the Haswell-E series only? Is there not a Skylake-E, or Broadwell DDR4 Quad yet? Are they on the horizon in the next 2 months?

That I3 option looks good as I see you can now OC these and not just the K series.

Broadwell-E is due out in Q1 2016 and Skylake-E won't be out until 2017 at the earliest.
 
Thanks for the advice everyone. In the end I got this:

i7-6700K (OEM)
GA-Z170XP-SLI
Savage Black 8GB (2x4GB) DDR4 PC4-19200C12 2400MHz
950 Pro 256Gb

Using existing Hydro 75, HD5450, CS450M.

All works great. Really nice speeds, stable, easy to overclock, good temps.
 
Surely that is only a very slight upgrade? I'm running two 4770K processors both heavily overclocked and running 2400MHz DDR3 alongside it and am only looking as Skylake-E and above as a viable upgrade.
 
Not to ruin your parade.

But that seems like you'll have gained about 5% increase in performance maximum. If you only need single core power, than an i3 overclocked would have been a cheaper and just as good upgrade.

There is also faster DDR4 RAM for a similar price.
 
No problem TRG.

The performance gains of some of the apps is 10%+ at like for like clock speed.

A bonus is that there is also more headroom for clocking. I could get the 4770k totally stable at 4.6, whereas this 6700k is looking good for at least a 4.8. Temps are way, way better.

I also prefer the bigger cache with the i7 over the i5s, i3s.
