looking to upgrade my cpu

i currently runniung as follows:

i7 950
16 gb ddr 3 triple chanel memory
evga 1080 ftw
asus rampage 2 extreme mobo
win 10

i want to upgrade my cpu however i am going to have to upgrade my mobo as well and possibly my ram. im looking at getting an i7 cpu with six cores from a one of the previous generations of i7's but i dunno what one and what the best choice of mobo and ram to go along with it. so can anyone help me out with some suggestions?
 
6700k I7 has 4 cores 8 threads on a z170 chipset 5820k/6800k has 6 cores and 12 threads on a x99 chipset, for gaming the 6700k is the better option up to dual gpu. If your planning tri sli which is not that good or need a cpu for with plenty of cores for programs/ renderring , etc then the later is a good option.

So what do you need ?
 
Seeing as you have a i7 950 on socket 1366 already I suggest having a look at the Xenon 5650/70 which depending on which motherboard you are actually using it could be a straight replacement and when overclocked it can give you a 4GHz+ 6 core 12 thread setup.

They can be found on popular auction sites for well under £100

There is also a large thread on here dedicated to them here.

i will be gaming, i currently have one gpu and maybe a second at a later date. i would like 6 cores but i would be willing to take a 4 core i7 if need be. im not looking for the best/newest set up but it needs to be pretty good.

You have to overclock the 5820k to about 4.5ghz to match the performance of the 6700k at stock, there is the 6800k but that isnt much faster than the 5820k and cost more.

6700k gets my vote .

Decision and budget please ?

Ok so heres a non overclcoking i7 wih a decent motherboard with plenty of fetures and 16 gb of ram.

My basket at Overclockers UK:

Total: £530.47
(includes shipping: £10.50)

thanks for that!
 
If overclocking is a definite no go area, then the 6700k has a 600Mhz clock speed advantage over the 6700 non k variant, also it allows for overclocking in the future.

There are 6700k motherboard bundles that OCUK sell to save a few quid as well.

This is not quite true the 6700 non k boost to 4 ghz while the k version boosts to 4.2 ghx effectvley 200 mhz diffrence.
 
Hi

I would personally recommend i7 6700k over any X99 based i7. I thought of buying X99 mobo+CPU, but when I saw many comparisons, reviews based on games using X99 and Z170 chipsets, 6700k just does it better for a lot lower cost.
 
You could get an i7 970, 980, 980X, or 990X. All are 6-core and all supported by your motherboard. Prices seem to range from £75 to £200+.

In my opinion though you'd be best off overclocking your 950 slightly which will cost you nothing and give you a good boost in some games. I wouldn't go for a totally new platform quite yet as you should be getting good performance with what you have.

What games are you playing and what screen res? What's the performance like?

Well I was going by the Base clock which is on the non K is 3.4GHz boosting to 4GHz and on the 6700k's is 4GHz bosting to 4.2GHz.

So for varying workloads it would be something like this.

6700k base clock speed 4GHz. Turbo boost is 0/0/0/2.

That means:
If 4 cores are being used, its max clock speed is 4.0 + 0*0.1 = 4GHz
If 3 cores are being used, its max clock speed is 4.0 + 0*0.1 = 4GHz
If 2 cores are being used, its max clock speed is 4.0 + 0*0.1 = 4GHz.
If 1 core is being used, its max clock speed is 4.0 + 2*0.1 = 4.2GHz



6700 base clock speed 3.4GHz. Turbo = 3/4/5/6
4 cores = 3.4 + 3*0.1 = 3.7GHz max
3 cores = 3.4 + 4*0.1 = 3.8GHz max
2 cores = 3.4 + 5*0.1 = 3.9GHz max
1 core = 3.4 + 6*0.1 = 4.0Ghz max
 
Xeon X5650/60/70.
Some cheap water cooler/ half decent HSF. I like the Fractal 120mm water loop.
3x8Gb of 2000mhz ish 1.5volt DDR3

You should be able to hit 4.2-4.4Ghz and have top tier performance with that lot.
 
Thanks Bru for the explanation, so turbo boost is not maxed equally across all cores on non k cpu's thats not commonly known.

Naughty, Naughty intel :(

Different SKU's have different turbo ratios, it is not just the k and non k chips.

All the info is here and here (and yes I know it is a wiki but I'm fairly sure it is accurate)

Not only that, the turbo speeds are different depending on the instructions being used. Specifically AVX instructions will throttle the clock speed (on Xeons at least).

Really??? Just curious as I'm looking at upgrading my fx8350 on the cheap, would a x5670 be a good choice? Seen them going for £50 on the bay, no idea if I could get a motherboard for them though
