Yup planning to OC with BCLK method. The site (overclocking.guide) advise on taking i5 6400 since it is cheaper. But seeing the difference just about ~RM60 compared to i5 6500, might take i5 6500 into consideration

GPU waiting for the upcoming review

CPU cooler i think just for the aesthetic LOL

Anyway thanks for your reply

Hi terence...
What do you think of this build ? Anything else i can improve on it ?

i7 6700k
Asus Z170 Pro Gaming
Corsair Vengeance LPX 16gb 3000Mhz
Samsung 950 Pro 512gb
Cooler Master V750 80+ Gold
Corsair Hydro H100i
Gigabyte GTX 1070
WD 3tb Blue
Corsair Carbide 400C
Acer XB271HU

Yes 6400 is cheaper but by adding another RM 60 for extra 0.5GHz bump on base clock on 6500 is very worth considering if the overclock fails (or not reaching the expected speed due to voltage limit, temperature etc), you still able to get > 3.0GHz where most of the games run better on faster CPU speed, especially single threaded games.

If you are hoping to get more frame rates from overclocking, you can consider opting for faster DDR4 RAM too, Skylake does benefit from the faster memory speed, Corsair Vengeance LPX 3000MHz RAM is a good start, just fire up the XMP profile in BIOS and you are good to go.

Hmm are you looking for full set (including monitor, keyboard, mouse, speaker etc) or just the rig itself?

Yup that is what i thought about i5 6500

For the RAM, do you means buy a 3000Mhz or 2133Mhz overclock to 3000Mhz via XMP? A 3000Mhz would be overbudget

RIG onlyyy

A locked i5 (non overclockable officially but overclockable "unofficially" via BCLK overclocking) on a Z170, are you planning to overclock the CPU? If yes then you have 2 paths, one with BCLK overclocking (i5 6500 is the best choice here due to higher base clock), another one is the 6600K which supports overclocking officially.

GPU battle - this one has to be decided next week because the review and benchmark (official one) of GTX1060 haven't released yet (19th July), but from the current info that we have, GTX1060 is more worth in money.

CPU cooler can be dropped to save cost if you aren't going to overclock the CPU.

if we are going to oc via BCLK overclocking, will it affect the CPU or MOBO negatively in terms of long term usage ? and any Z170 mobo can be used for that purpose ? 

Get a 3000MHz RAM, but that's just a pure suggestion, not necessary need to follow, Skylake CPU runs better with faster RAM, that's it, if budget cannot fit then just stick with value RAM (2133MHz).

Edit: BCLK overclocking will mess up the speed of other components too, especially RAM speed, value RAM is not meant for overclocking, so you need to monitor the temperature of the RAM (and voltage too), if it gets too hot then please return to stock speed or reduce the BCLK multiplier to avoid any potential damage to the components.

Generally will affect CPU only since Z170 mobo is made for overclocking but non-K CPU isn't.

Light BCLK overclocking is fine, if you are looking to squeeze out another 1GHz in the long run on non-K CPU then you better get a K CPU, it is more suitable for heavy overclocking via multiplier.

ohhh, by doing some light BCLK overclocking, how much did you mean ? As it will affect the CPU, i should better off w/o overclocking mine 

First, check if your Z170 mobo model has the non-K CPU BIOS update released or not, if yes, update it.

Locked CPUs have their multiplier locked down by Intel, meaning you can only increase/overclock the speed via BCLK, it depends on the stability of the CPU (lottery time again) and the temperature, I won't recommend going over 4.2GHz though.

Beware that overclocking via BCLK will also affect the speed of other components as well such as RAM speed.

What's your main usage?

Going from i7 4790K to i7 5820K (or the latest i7 6800K) won't improve the gaming performance significantly, some games will have the frame rate reduced due to lower clock speed of i7 5820K because most of the games are still single threaded where the performance of single core is still the main important factor, we are still miles away from multithreaded games, hopefully DX12 and Vulkan can help to speed up a bit (lower CPU overhead) 

I won't recommend you to go from i7 4790K to i7 5820K/6800K unless your workload is heavily dependent on CPU.

My main usage is mostly gaming,
main reason to upgrade is for DDR4 and GPU upgrade and SLI only.
if that whut sifu said maybe i just go for GPU upgrade only.
thanks for advice~

I'm considering either the Asus R241Y at RM500 or Dell U2414H at RM800. Is the RM300 extra of the U2414H worth the price? Both are similar and both are non glossy

Dell UltraSharp is more premium and supports pivoting (portrait mode), the panel used on U2414H is also better than R241Y.

The price you listed is quite cheap, it is selling over RM 620 for R241Y and RM 920 for U2414H (RRP is RM 1065) from what I've seen here on the Internet 

Thanks bro . The Acer price is through Gemfive with discount while the Dell is through Lelong seller based in PG.
Don't know whether the RM300 extra is worth the investment. I do use DP, but i can use an adapter. Decisions decisions
