    Okely dokely :thumb: .

    Currently if I was doing a Skylake build I'd be contemplating:-

    i5 6600K (~£200)
    Asus Maximus VIII Ranger (~£145)
    DDR4 ~2400MHz+ (probably 16GB, 8GB be ample though but as currently ebuyer have HyperX Fury 2400MHz 16GB kit £57 I'd get that)

    If going 4K now and I would like FPS of min ~60 I'd opt SLI 980 Ti, as review data state total system usage with them OC'd = 652W coupled with an i7-5960X@stock on X99 platform, I'd think a good 850W PSU be ample, worst case look for 1000W on promo.

    Why the Fury X hasn't come into the equation is I'd probably wanna replace the stock AIO cooling for custom loop due to:-

    a) rad is 12 cm wide, and 15.5 cm tall so I reckon I may run into an issue of mounting 2x those on same surface close together.
    b) may not like 2 sets of pipework around case.

    By going 980 Ti I reckon I could still be on air (save some £££ vs CL with Fury X CF), with good airflow in case I'd think temps/noise not be an issue. CPU again probably air cooler and not custom/AIO water solution, probably aim to get an Archon SB-E X2 2nd hand (which I did for my i5 4690K rig ~£13.50).

    Excluding PSU and other bits I reckon that's about £1400, what is budget?

    Also I reckon that's the end of getting gold bullion but maybe differing set of questions from SWMBO ;) .

    Is it worth upgrading i5 2500K to i5 6600K? My opinion, well no. When considering that the Skylake cpu launch by intel was messed up. (they should of released it before X99 cpu) and its main selling point was that it supports ddr4.

    I use a Intel Core i7 4790K, S 1150, Haswell Refresh, Quad Core, 4.0GHz Base, 4.4GHz Turbo, 1250MHz GPU, 88W, CPU which is still the true gamer cpu of choice due to being a great cpu to overclock (4.8ghz) (gaming benefits from a high frequency not extra cores) and runs cool because of it 88W, it has Hyper Threading and ddr3 ram is super cheap.

    Now compare this to Intel Core i5 6600K, S 1151, Skylake, Quad Core, 3.5GHz, 3.9GHz Turbo, 6MB Cache, 1150MHz GPU, 35x Ratio, 91W. First thing is that its uses a bit more power, so not as efficient as old socket, it does not have Hyper threading so its a quad core only (no logical cores, unless you buy the Intel Core i7 6700K) and the prices for the motherboards that support this cpu start at £70+ with the top end at £400+

    VR is more about the GPU power, as long you got a a high frequency cpu you be fine.

    Agree with your post, but HT from what I'm aware doesn't help gaming, so therefore would deem an i5 best buy.

    I run an i5 4690K @ 4.9GHz CPU @ 1.255V 4.4GHz Cache @ 1.10V plus 16GB (2x8GB kit) @ 2400MHz @ 1T (11-13-14-32) on air 24/7, using ThermalRight Archon SB-E X2. With ambient temps of 22-24c = max about 73-78C when stability tested.

    Yes I wouldn't run Prime 95 (AVX versions) but have done RealBench stress mode 8hrs/x264 v2.06 8hrs/f@h on CPU & GPU 24 to 48hrs (all many times); previous i5 4690K would do 4.6GHz@1.27V (minimum tests done); some info in this post on OCN.

    TDP I'd guess on Skylake is higher due to the higher performance IGP. Z97 boards are not available new in same abundance of SKUs when I last checked. Z170 isn't really that much more expensive than Z97 now, DRR4 is pretty much same price as DDR3. There are a few other benefits to Skylake/Z170 besides DDR4. Currently couldn't really justify suggesting Z97 build a) due to reasons above b) smaller gap of performance/features gain vs Skylake.

    If in OP shoes I'd either stick with current setup and upgrade GPU or just go Skylake as that seems to be his wish and like stated use old rig as spare for his LAN parties.

    Fair point. In my case I do use HT as I video edit\render and also fold for Custom PC & bit-tech folding team. So I picked 4790K as it did all of the above and more. DDR4 prices have come down of late but the top spec Z97 board versus a Z170 there a good £150-£200 difference in price and for me that is the deal breaker.

    If I was to upgrade my system, i would go to X99 platform as at least it would future proof it a bit.:thumb:

    I will probably be going for the following.

    Core i5-6600K 3.9GHz (Skylake) Socket LGA1151 Processor - Retail
    Maximus VIII Hero Alpha Intel Z170 (Socket 1151) DDR4 ATX Motherboard
    Avexir Impact ROG Series 16GB (2x8GB) DDR4 PC4-21300C15 2666MHz Dual Channel Kit
    Super Flower 850W PSU Modular
    Carbide 600C Full Tower Inverse Gaming Case
    Water/Rad AOI for the CPU
    250GB SSD for OS
    1TB SSD for Games
    Possibly a single 980Ti AIO or I may get two but I may just hold out for Pascal still undecided. The GFX is my biggest issue right now as im 100% on everything else.

    As mentioned above HT is not needed as I do not video edit/encode so ill stick with 6600k

    Agree I'd consider that vs Skylake (X99 is :cooldude:).

    SuperFlower great PSUs (Leadex), besides other aspects love the low ripple. EVGA G2's OEM is SuperFlower (Leadex platform), IIRC longer warranty is plus with them.

    Yes the M8 Hero has more phases (didn't read about features and IIRC true phase count) but in CPC group test M8 Ranger matched it for CPU frequency and same VCORE so I'd pocket the saving and have that TBH (but your build ;) ).

    For a time I wanted to swap my M7 Ranger for a M7 Hero but after getting other i5 4690K it was clear the mobo was not holding it back ;) .

    Avexir Impact ROG Series 16GB I couldn't justify for £££ TBH, G.SKILL Ripjaws V Series F4-3200C15D-16GVR 16 GB (8 GB x 2) DDR4 3200 MHz CL15 Memory Kit - Blazing Red @ pre-order Amazon for ~£75 I could :rock: .

    The ram was a quick reference I ideally want quicker RAM but want the LEDS on the ram for the effect....thats for the kid thats still inside me :D

    The motherboard choice is because of few other features the board has like the sound/rgb strips etc etc.

    The intel 2000 series is a little long in the tooth, however, the biggest reason to upgrade since then is greater I/O and bus performance with newer motherboards. For example, you do not have PCIe version 3 and the next generation Nvidia Ti series could benefit, especially if you are currently using 8 lanes of your PCIe version 2. USB 3.0 is also a nice upgrade. Not to mention the current extra 4 PCIe lanes to help you keep all 16 PCIe lanes for your video card.

    Intel cares much more about the GPU next to their CPU, not the CPU speed [performance] compared to older CPUs, including overclocking, and each newer CPU is only very slightly faster than the previous, at the same clock rate. Remember, you will most likely never find an intel 6000K series CPU that will hit 4.7GHz, most people are happy to hit 4.4GHz. Overclocking smaller nm construction is much more difficult than larger nm CPUs from the past.

    If you're going I7 get a 5820k. It's that simple :)

    Im not too sure on the differences to be honest im not up with CPU specs these days I've been out of the loop for some time.

    They that much quicker? I know its 6 cores but will that matter for gaming?

    I'd go for it purely just for futureproofing. Hell - I went bonkers and bought a 5960X!

    I don't fancy adding another £600 onto the bill :)

    And that brings me to point 2 - future upgradability (yeah I know Chrome, that word doesn't exist).

    With a 5820k you have the 5960x 8 core and then the entire Broadwell E range (incoming) including a 10 core.

    OP - Haswell E is kinda like a 6 core+ Devil's Canyon. So whilst it loses a little in IPC over Skylake it absolutely smashes it in threading. Obviously threading was somewhat important for you to have picked out the Skylake I7 but the SL I7 is hardly any cheaper than the 6 core 12 thread 5820k so it just makes no sense.

    4 cores is sort of a minimum for gaming now, but things are slowly improving.

    I don't blame you. If I were speccing a 'sensible' i7 rig at the moment, I'd go 5820K. It's a great chip.

    ATX? X99 Deluxe, without a shadow of a doubt. There are cheaper options available - but I really think it's a solid board. Mine is currently the heart of my ESX box.

    There are a few in the mid range that pack a decent punch. I'm using some b-tard Alienware MSI thing that's very similar to this -

    https://www.overclockers.co.uk/msi-...cket-2011-ddr4-atx-motherboard-mb-301-ms.html

    And it handles everything fine (two Fury X in CFX and a RAIDR X4).

    I also hear good things about this board, if you wanted to go MATX

    https://www.overclockers.co.uk/asro...011-ddr4-micro-atx-motherboard-mb-135-ak.html

    Do note though, OCUK seem to have upped their prices by about £20 which is a bit cheeky so feel free to look elsewhere :) If you like a bit of orange this is a fantastic board.

    https://www.overclockers.co.uk/giga...ket-2011-ddr4-eatx-motherboard-mb-520-gi.html

    The X99 deluxe is obviously a lot better, but that comes at a price which I feel isn't worth it for a 5820k.
