Build first gaming PC from scratch, please help (Australia)

What motherboard and Case do you plan on using?

The Kingston A400 is not a great option for your Windows OS. It will still be quicker than a HDD for sure, but the response time can get bad sometimes when it's in use. (I've used it in many budget builds)

If you can get a better processor for $40 - $50 I'd do so. It's not a bad processor, but it will have a hard time pushing 144 hz.

What is the maximum you are willing to spend? Also, I understand in Australia some things cost much more than here in the states, so if I say something that's unreliable, let me know. What site are you planning on buying or is it local? With this kind of information I can help you better.

First figure out: headphones, monitors, keyboard, mouse and controllers.
Then subtract this for the budget for your PC.

Second: Figure out which motherboard you want. If you want it to have Wi-Fi, support for AMD or Intel processors, SLI/Crossfire, USB 3.0, USB Type C, etc.

Third: Get a case that supports these features. Make sure it fits your motherboard. For example, don't get a mini-tower for an ATX board. I usually recommend first time builders to get a full-tower, as it allows you more space to run cables, work inside, fans and future upgrades.

Then last: Use the remaining budget on your other components.

- If your motherboard supports m.2, I would get that instead of a SATA III SSD.

- Graphics Card / Processor. You want to get a Processor that can push 100+ FPS in games and a GPU that can run High settings. I recommend a i7-7700 and a 1070 minimum in your case.

- RAM - just make sure it is supported by your motherboard. Usually you want at least 2666 MHz.

Hi mate, not sure if you are still in the game or if you've decided already but my local builder in SA might help.

This one kinda fits the bill quite well, built for you though.

You should get 2x 4GB RAM (or even 4x 2GB(?), depending on your motherboard). It should be slightly faster since it will be a dual-channel setup.

I recommend that you get a power supply with an certified efficiency rating (e.g. bronze or higher). I've got a Corsair CX450M (bronze) and it's semi-modular so there's no "excess" cables sitting in the tower.

I have a Razer Deathadder 2013 and I really like the mouse, however, after I started using it for a while, the mouse wheel became noisy when scrolling up and it was annoying but i've got used to it.

Also, don't forget about a wireless card

Few words

CPU
Put in i3-8350K which is 4 core/thread CPU and which is more than enough for your gaming needs @ 1080p. Best part about this CPU is that it's far cheaper than i5-8400 and you can also overclock the CPU if you so desire.

CPU cooler
Since CPU doesn't come with one, put in Arctic Freezer 33 eSports which is one of the best mid-sized air coolers. CPU cooler comes with 2x fans in push-pull configuration and it has black & white theme to match the build's theme.
(I too have Arctic Freezer in use with my Skylake build but i have the predecessor of Freezer 33 known as Freezer i32.)

MoBo
Picked a MSI Z370 chipset MoBo which shares the build theme. Thanks to the Z370 chipset, you can OC your CPU and also run faster than 2666 Mhz RAM. Oh, MoBo also has MSI Mystic Light RGB if you plan to add some RGB peripherals (fans, LED strip) at some point.

RAM
Put in 2x 8GB 3000 Mhz RAM which totals at 16GB, more than enough for today's gaming needs. And due to Z370 chipset MoBo, you can run your RAM at speeds of 3000 Mhz just fine. Oh, RAM also has CAS Latency of 15 which makes it more responsive than RAM with CAS Latency of 16.

SSD
While you picked 240GB SSD, i stepped it up to 500GB one. Also, selected Samsung 860 Evo since it's one of the fastest 2.5" SSDs currently out there with affordable price.

HDD
Upgraded that one too. You picked 2TB HDD, i put in 3TB HDD. Toshiba drives are also more reliable than Seagate or Western Digital drives. Only HGST (Hitachi) HDDs are even more reliable than Toshiba HDDs.

GPU
Put in MSI GTX 1060 Armor 6GB which shares the black & white theme i created within this build. With GTX 1060 6GB, you're looking to play at high/ultra settings @ 1080p with solid 60+ FPS.

Case
Since choosing a PC case is personal choice, i left it to the one you already picked.

PSU
All that greatness above is powered by good quality Seasonic PSU. Focus 550 has 80+ Gold efficiency and it comes with 7 years of warranty. PSU is semi-modular, making cable management far easier than with fully-wired PSU.
(All my 3 PCs: Skylake, Haswell and AMD are also powered by Seasonic. Full specs with pics in my sig.)

OS
Put in Win 10 Pro 32/64-bit. Not much to say here, only that with this version and during OS install, you can decide if to install 32-bit or 64-bit one (pick the 64-bit one).

KB, mouse and headphones
Since choosing those is also a personal choice, i left them as you picked them, except the headphones.
You selected the Corsair VOID Special Edition. While the yellow color does stand out, paying $65 for that yellow color alone is in my opinion a waste of money. So, i replaced the headset with Corsair VOID Pro RGB USB which is the 2nd generation of VOID headsets from Corsair. If you so desire to get yellow headsets with steep price and worse mic than VOID Pro, feel free to switch them back to the one you initially picked.
(Oh, i too have the Corsair VOID Pro RGB USB headset in use with my Skylake build as well.)

Extremely powerful. Nearly 150% more powerful than GTX1060 PC. No compromise build. All very high quality components.

I would never ever even consider the i3 8350k, its a stupid amount of money for what is essentially a last gen i5 quad core.

I agree, if you're streaming you'll need a higher core count to stream and game at the same time. Especially if you take in consideration that new triple A titles like Black Ops 4 makes use of all 8 cores 16 threads. Otherwise the CPU will be constantly pegged at 100% usage and you'll have stuttering in both the game and streamed content.

@kenzy9 you stated you want high refresh rate, but at what resolution? Are you going to keep it 1080p?

Orientated towards Value but still mm offering great performance & all parts are good quality.

The 1070ti is your bang for buck option if looking at running 1080p resolution.

Just because you don't find any value in that CPU doesn't instantly mean it's a bad CPU for everyone. i3-8350K has the best price to performance ratio among Intel CPUs, making it the value king. And while it has equal performance to i5-7600K, i3-8350K is a lot cheaper. For brand new i5-7600K, you're looking to hand out $250 USD while for brand new i3-8350K, you're looking to hand out only $169 USD.


Tell me this, how on earth people managed to game and live stream before Intel 8th gen CPUs came out? Since before that, most consumer grade CPUs were 4 core CPUs. Except Core i7 which has hyperthreading.

Times have changed. Games are now making use of extra cores/threads (More than 4 Cores/Threads). That is a system i'd recommend for ESPorts titles, but not for triple A and definitely not for streaming.

With the possibility of streaming, I would go with an R7. The 1tb SSD is for game storage.

Changes made compared to my 1st build suggestion:
CPU: i3-8350K -> i5-8600K
GPU: GTX 1060 6GB -> GTX 1070 Ti
KB: Razer Cynosa Chroma -> none
Mouse: Razer DeathAdder Elite -> none
Headset: Corsair Void Pro RGB USB -> none

The rest of the components are same. With that build, you're looking high/ultra settings @ 1440p (2K) with 60+ FPS and due to the CPU's 6 cores/threads, you can also live stream during gaming without issues.

I've just skimmed through previous messages without reading them, hopefully I won't be abused too much .

So, for 144 Hz gaming and streaming, the 8700K would be...not exactly ideal, but it's a decent choice that will pull off the job just fine. The 1060 really won't cut it, but I haven't swapped it out yet. But your first priority should be to get a better GPU, at least a 1070 if not a 1070 Ti. Other than that, I've changed pretty much everything from the original build except peripherals and HDD, so have a look at it. Again, this isn't final, if you agree to it then the GPU shall be upgraded to a 1070 and the rest of the components shall be downgraded to make room for the 1070.

if its a complete setup :

Here is a nice build within your budget. You can get many of the parts cheaper if you shop around. I chose an air cooler, which works fine with a mild overclock/stock settings. I don't recommend any water cooling as it is your first build. Also, make sure you work out the monitor/ accessories yourself, I just a chose a popular monitor most people choose for 1080p 144hz. (I have one too)

https://pcpartpicker.com/list/mbG24q

This system is an alternative to the excellent builds mentioned above and will give you many years of gaming/streaming, not to mention a viable upgrade path for all of your internal components. One of which is the processor as AMD's AM4 platform will be supported until the year 2020. People are most likely going to respond to this post "why first gen Ryzen?" As far as i'm concerned this is the budget king for streaming, allowing you to multitask and utilize all eight core/16 threads at a reasonable price. Choose this option if you are on a budget and would rather prioritize smooth playback for simultaneous gaming and streaming over high refresh rate gaming. If you must stream and play games at a high refresh rate, you'll have to pay a premium to match FPS with a high refresh rate monitor. If that's the case my recommendation is an i7 8700/8700k/i9 9900k build. However based on your original post, I get a sense that the following might be more in line with your budget:

Here's why the Ryzen 7 1700 is still the best value for the money (Video is USD but you get the point):
https://www.youtube.com/watch?v=yvypWSTaoJs

I personally have one myself and Call Of Duty Black Ops IIII uses all eight cores sixteen threads. If you're streaming the extra processing cores will come in handy. When streaming on a budget, I often explain it's better to prioritize smooth playback over high FPS and high refresh rate because builds like that cost a premium. Let me know if you're interested in premium Intel builds for streaming.

That's correct, if you aren't overclocking you can save money by purchasing non-overclockable parts. For example, you could go high end on the processor and lower end on the graphics card now. In the future upgrade the graphics card and monitor, enabling you to go with a more premium high refresh rate build:

Going with this build will give you the processing power to hit higher FPS to match your future monitor's high refresh rate and you'll have 12 threads to assist with the additional overhead involved with streaming. Intel has a superior ring bus architecture and 1ghz+ boost clocks over AMD, as well as the fact that most games are better optimized for Intel (Though games are starting to improve optimization for AMD). The AMD RX 580 will give you adequate performance in triple A titles which will be plenty for your 60hz 1080p panel (Way more in ESports titles) and the 8gb of VRAM will ensure the graphics card stays relevant, until it's time to upgrade the graphics card and monitor.
