New PC build: your opinion

how did you get 12 gb of ram and I don't think ddr 3 should work with that mobo in the first place.

good choice

• Get a I5-6600K even if you don't plan overclocking now it's just a small different amount.
• Why 12 GB instead of 16 GB of ram?
• I would get a 2 TB HDD personally, just a bit more money.
  EDIT: which power supply are you getting?

No problems with the rest, but 12 GB RAM? I take it this is coming in 4 GB sticks? May be an issue if you ever want to upgrade RAM as you'd be replacing 4 GB sticks with 8 GB and losing value.

12 GB RAM is kinda weird. why not get 16 gigs? most modern games demand 8 gigs and recommend 16 anyways, so you might consider getting those.

Also, you might consider getting the 6600K instead as it has a higher clock speed and offers overclocking ability.

And I would consider getting a 500GB instead as those offer more value per GB than 250 GB models. You could install multiplayer games on it, then which would cut down on loading times significantly.

You selected a "Z" motherboard with a "non-K" CPU.
"Z" motherboards are meant for overclock, which can only be done with "K" CPUs.
Ditch the "Z" motherboard for a "H" one, and with the extra money you would be able to up the RAM to 16GB, and maybe even get a 500GB SSD, or a bigger HDD.
Also, as mentioned, these new motherboards only support DDR4 RAM.

I would go for a ddr4 board instead, more future proof.

Definitely get a sound-card on board if you like music or sound effects in your games!

The Sound Blaster AWE32 is pretty sweet if you can afford it!

get 16 GBs DDR4 RAM at least, my advice wud be Gskill, one of the bests! if u don't plan to do OC, why get a Z170 Mainboard? and your VGA wud be good for 1080p gaming for now, and buy a at least a 500-600 watt PSU

ditch the Z board if you are not using a K series chip - also DDR4 required

Extra advice: don't cheap out on the PSU, it's the most important part for a PC.
Choose a renowned brand like Seasonic, Fortron/FSP, EVGA, Thermaltake, Antec, just to name a few of the best ones.

Change the motherboard to the Z170 Extreme3 or Extreme4 and get a DDR4 RAM. The Skylake platform was designed with DDR4 RAM in mind, it just offers backward compatibility for extreme circumstances.
Or, to save money, get a H170 board. Z170 is needed to overclock, H170 is more than enough for any single or dual GPU build (although it may be a little slim with an M.2 SSD added as well).

That 12 GB sounds like 3×4 GB sticks. Unless you are carrying it over, don't use them, since it will put the motherboard into single-channel mode automatically. If you are buying them new (and for DDR4, you most likely will), get 2×4 or 2×8.

For CPU, either get the 6600K to overclock or just stick to the 6500 to save money. The difference between the multiplier-locked 6500 and 6600 is next to nothing in performance, but way too much in price.

looks great

though that motherboard and CPU match doesn't make much sense, you could get a cheaper one or an overclock-able CPU

How much do you think this is going to charge you?

I don't really want to be that guy but have you considered just using the Logicalincrements build guide and modifying based on prices?

As people said about the motherboard, if you get a cheaper one, try to get a 500gb SSD if you could afford with the change

CPU: Intel Core i5-6500
Cooler: EKL Alpenföhn Ben Nevis
Mainboard: ASRock H170A-X1/3.1
Ram: Kingston HyperX Fury DIMM Kit 8GB, DDR4-2133
PSU: be quiet! Straight Power 10-CM 500W
HDD: Seagate Barracuda 1TB
SSD: Crucial MX200 250GB
GPU: MSI GeForce GTX 1060 Gaming X 6G

you dont need a Z board without a K Processor

Not sure if joking

You can't stack ddr3 ram on skylake mobo

ASUS DUAL-GTX1060-O6G

The GTX 1060 don't support SLI, so why are you getting dual GTX 1060s?

how many does it cost all?

You should get 1070gtx minimum. It's 2016 outside :) or last gen gtx980ti maybe, if it's selling for good price in your country

DDR3? i really recommend moving to DDR4, even if its just 8GB, it will run better, and why are you going for a Z Motheboard if you dont have a K processor? any special reason?, the Z170 is only worth it if you are going to use a K processor, otherwise a H170 or B150 will do the job as good as that Z170.
