Complete Build Breakdown
When you’re picking parts to build yourself a gaming PC there are a lot of considerations to keep in mind. Do you plan on upgrading it in the future? Do you just want what you can get now, or do you want to eventually overclock your processor? Each path potentially poses a lot of new considerations if your goal is effectively balancing price vs performance.
But, why do all that when you could have me do it for you?!
Case: Holding everything together is the Thermaltake Versa H18 micro-ATX case. It gives you lots of options for expansion in terms of added storage, or a more intensive cooling profile.
The H18 comes with a total of 3x front USB ports as well as 3.5mm headphone and microphone jacks. It’s also boasting a tempered glass side panel and a full PSU shroud. The compromise being it only comes with 1x 120mm fan – 1 is pretty much good enough for this build, but you might want to add 1 more.
There are A LOT of other cases that would work for this build, I really suggest that you take a look at some other options just in case you can find one that you like more! If you need some suggestions, check out what I consider the 5 best mATX cases!
CPU & Cooler: AMD’s R5 3600 is a complete beast when it comes to gaming, streaming, and pretty much anything else. With a sub-$200 price tag, the R5 2600 simply cannot be beaten in terms of price vs performance.
It’s loaded with 6 cores and 12 threads that’ll operate at a modest 4.2GHz by default. Since the R5 3600 fully supports overclocking, you could easily squeeze out even more performance if you don’t mind spending some time testing.
The R5 3600 comes with a good CPU cooler if you’re not pushing your CPU too much or overclocking. Upgrading to a larger air cooler would be recommended if you’re going to overclock.
Motherboard: The MSI B450-A Pro Max ATX motherboard is a great choice at this level that’s loaded with all of the features you might need for an AM4 socket build like this; including 6x USB ports, 6x SATA ports + 1x M.2, integrated audio, 2 case fan headers, room for 4 sticks of RAM, a built-in ethernet controller and lots of room for future expansion.
The B450 chipset does support CPU overclocking, which means you’re free to crank up the power on your R5 3600 assuming you have adequate cooling.
Graphics Card: AMD’s new RX 5700 and its 8GB of GDDR6 VRAM is a complete and utter powerhouse when it comes to 1080p gaming – it’s also capable of tackling 1440p without a problem while pushing 60fps in most games.
Gigabyte’s RX 5700 Gaming OC is absolutely no exception. It runs quiet, cools great, has 4x display outputs (3x DisplayPort, 1x HDMI), and easily fits inside almost any case with ease. It’s very capable of 1440p 60fps gaming in any game out there and it can easily support VR headsets like the Vive or Rift.
RAM: 16GB of RAM is the perfect amount for a gaming PC at this level. With that in mind, this build is running 2x8GB sticks of Corsair Vengeance LPX at 3000MHz. This leaves you with lots of room for future expansion and if you wanted to run more than 16GB that’s completely possible – when you do upgrade try to stick to the same speed as your RAM will automatically change its speed to match your slowest stick.
Power Supply: EVGA’s 550 BQ fully-modular power supply is a good, reliable, power supply. It’s rated to 80+ bronze and comes with a 5-year warranty + 24/7 technical support from EVGA. Being fully-modular, you don’t have to worry about hiding unused cables – you just plug in what you’re using and leave everything else in the box.
Storage: When it comes to storage, there’s a Kingston A400 480GB SSD in this build by default. Beyond that, you can easily add up to 3 more drives based on what the motherboard will support. All you’ll need are extra SATA data cables and the additional drives themselves.
If you don’t already have the base peripherals like a monitor, keyboard, mouse, and some kind of audio, you’re definitely going to not only want these things, but need them. Below we’ve featured an awesome product to represent each of the fundamental extras that you might need!
Picking the best monitor for your usage is often very subjective, beyond the basic specs you should be looking for that is. With such a wide array of different designs and price points, it pays to do some research. That’s why I put together this guide on how to pick the best monitor for gaming!
Even more important than picking a good monitor is picking a good chair. If you can’t get comfortable because you’re using a bad chair, you’re simply not going to enjoy your gaming sessions as much as you should be. To ensure you can get the most out of every session, I put together this in-depth buyers guide of all the best gaming chairs!
ASUS VS247H-P 23.6″
23.6″, 1080p 60Hz, 2ms response time – Great for gaming
Redragon K556 RGB
A good full sized mechanical keyboard with RGB backlighting and a very attractive price point.
Logitech G502 Hero
One of the absolute best gaming mice you could buy. The G502 is a tried and true platform that’s only been improved to where it’s at now with the HERO.
HyperX Cloud 2
The HyperX Cloud 2 headset is undeniably one of the best you could own. They use audiophile-grade headphones with a high-quality detachable microphone.
The operating system you pick should be based on your necessities, or how much extra cash you have lying around. If you need something that works right out of the box with very little tinkering required, Windows is what you want, but keep in mind that it’ll cost around $100 to go this route.
When it comes to getting access to the widest range of compatible programs, games, etc, Windows is your best bet. There are a few options available, but the one you’ll want to consider first is Windows 10. It’s the only OS that supports DirectX 12, and you’re definitely going to want DX12 as it becomes used in more and more games.
For the more frugal or privacy concerned users, a Linux based O/S like Ubuntu might just do the trick. Linux has been dubbed the “most secure” operating system when it comes to spyware, etc, so if that is a concern, it’s just another reason to grab a free copy of Ubuntu.
When it comes down to actually installing your OS, you basically have 2 options. Either do it from a DVD/CD or create your own bootable flash drive loaded with an OS installer. In my opinion, the first option is a lot easier, but you’ll need to grab the DVD drive I have listed above.
The most recent version of Microsoft’s operating system, Windows 10 is your best bet for across-the-board compatibility.
Ubuntu is a great, open source operating system rooted in Linux. It’s known as one of the most user-friendly and easiest to learn.
Since the motherboard in this build does not have built-in WiFi (most don’t) you will need a WiFi adapter if you plan on using a wireless internet connection. That said, if you have the option to run a wired connection, do that instead because it will be faster & more reliable.
Since there are tons of options available when it comes to picking a WiFi adapter, it can be a little confusing at first; but don’t worry because I’m going to help sort that out… Or, at the very least, I’m going to try to make it as simple as possible.
Basically, if you have a newer router/modem, chances are it’s on the AC protocol and supports both the 2.4GHz and 5GHz bands – perfect. If it’s older, it might be on the N protocol which is a little slower than AC, but your modem/router might still be new enough to be “dual band” and support both 2.4GHz and 5GHz. This is the first thing you want to figure out – search the model number which will be stamped somewhere on it if you’re unsure what you’re running.
Next, it’s basically just a matter of matching numbers with numbers and letters with letters. If you have a dual band (2.4GHz + 5GHz) modem on the AC protocol capable of 1300Mpbs, you want a dual band AC1300 adapter.
Internal WiFi Adapter
TP-Link Archer T6E
A good internally mounted (PCIe) AC1300 WiFi adapter. Make sure your build has enough room!
External WiFi Adapter
A reliable AC1300 USB WiFi adapter. Capable of operating on both the 2.4GHz and 5GHz bands.
When everything is said and done, this machine is a beast and it will absolutely dominate any game you decide to play in 1080p 60-100fps+ (way more in most games) and it’s also going to do well in 1440p @ 60fps. Whichever route you go, you can rest assured that this build has the power to handle it effectively.
If you came here looking to build the best $900 gaming PC that will last you into the future of modern games, you’ve found the right build. This beast features quite a bit of upgrade potential and a lot of raw power, so what are you waiting for?
