One of the first things to consider when planning a new gaming desktop build is what resolution you’ll be playing at as it plays a huge role in how powerful of a system you’ll need. In our recommended PC builds you'll see that we categorize our suggested gaming builds by resolution because your PC gaming resolution is the biggest factor in how much you need to spend.
Firstly for any PC beginners who may be wondering, what exactly is resolution again? Simply put, resolution refers to the amount of pixels rendered on a screen. When you choose a monitor for your gaming PC, you have to decide which resolution monitor you want to get, as while you can change the resolution of a monitor, you ideally want to stick a monitor's native resolution. But why is the screen resolution important in gaming?
Higher resolutions render more pixels on screen, which results in better quality images. This comes at the expense of taxing your computer hardware more, so the higher the resolution you play in the more powerful (and therefore more expensive) of a gaming computer you'll need to be able to run that resolution at a smooth, playable performance level. If your PC is not powerful enough to run a certain resolution, your performance will suffer and you'll get on-screen lag or slowdowns which can get in the way of your enjoyment of the game.
Plus, as well as needing better (read: faster) PC components for higher resolutions, you’ll also need a monitor that supports that resolution, and high resolution monitors can range from quite a bit more expensive to insanely more expensive. For example, 4K monitors aren't cheap.

What is 1080p?
1080p, also known as FHD (Full HD) has 1920 x 1080 pixels on-screen and is the common standard these days and the most popular resolution among gamers. In this era of gaming it has the best quality to price ratio. In other words, 1080p/FHD is the sweet spot. If you're on a budget, or looking to get the highest frame-rate possible for use on a high refresh rate monitor such as 120/144Hz, stick with 1080p. It's still a good quality gaming experience.
What is 1440p?
The next step up in resolution from 1080p is called 1440p which is also sometimes referred to as either QHD or WQHD, and has 2560 x 1440 pixels on screen for even higher quality graphics. If you’re wondering, the Q means that it has 4 times (Q = a quarter) the pixels of HD/720p (not to be confused with FHD). As for the W which some people use when referring to it, that simply means Wide as it’s a wide resolution format, however it’s unnecessary to include the W to denote it as a wide resolution because all the resolutions are wide.
1440p takes a more powerful PC to run real well than 1080p, but not by too much in many games, so one day it'll overtake 1080p as the sweet spot. Some will argue that in 2018 1440p already is the sweet spot, assuming you're not on a super tight budget when building your PC.
What is 4K?
Moving on from 1440p and there’s 4K which is 3840 x 2160 pixels, and also called 4K UHD. Whilst 1440p performance is quite doable if you have a nice amount to spend on your rig (ie over $1000 at the least), 4K is generally not recommended as its requirements are just too high for the average gamer and a decent 4K monitor will cost you a lot.
By all means, opt for a 4K gaming rig if you have the cash to splash, but just know what you’re getting yourself into - especially if you’re a picky gamer and not just wanting playable 4K performance but you’re aiming for a super smooth playing experience in demanding modern titles.
What is 720p?
As for dropping down from 1080p, you have 720p which is also known as HD (1280 x 720 pixels) which used to be the PC standard back in the day, this might be worth considering if you’re building a real cheap entry-level gaming PC build and/or if you don’t mind lower quality graphics. Some games are absolutely fine in lower resolutions such as 720p, and in some eSports titles you'll find some players preferring to sacrifice graphics quality to get a higher, smoother frame rate. For most gamers though, assuming your budget is at least the standard mark of around $400-$500 and higher for your new computer, you should probably just stick with 1080p as it’s very achievable to get good performance in 1080p these days.
1080p, 1440p, 4K and poor old 720p are the 4 most popular PC gaming resolutions right now, but which is the most popular resolution in 2018? Glad you asked.
After that you have the rarities such as those using a different aspect ratio and resolution of like 900p (hey, if it works for you and your game supports then go for it), and the crazy (smart?) gamers lucky enough to afford a monster $3000-$5000+ gaming monster capable of a mega 8K resolution.
Simply put, yes. 4K has so many more pixels on screen than 1080p, which makes for a much higher quality image. Of course, this obviously comes at a cost in needing much better hardware, so a high resolution like 4K is out of reach for many PC builders especially if you're on a budget. 1080p and 1440p is absolutely fine in 2018, and still provide great graphics as there's still a heck of a lot of pixels being rendered in those resolutions. But if you have the cash to splash on your gaming desktop build and you want the most immersive, highest-quality graphics possible, then once you game on a high resolution like 4K it'll be hard to downgrade back to 1080p or so 'cause it's simply beautiful.
Although, deciding which resolution to build your PC for and choosing between 1080p vs 4K (or between 1080p and 1440p, or 1440p and 4K) will also depend on the types of games you play as well. For example, in a game like CSGO, Overwatch, Rocket League, DOTA 2 and League of Legends, where it's mostly about the fast-action gameplay rather than taking in breathtaking landscapes and graphics (glance around for a second in CS and you're bug squash), you could argue that the gaming resolution you're running doesn't matter so much and won't change your overall experience much (if at all) 'cause it's solely about the gameplay.
Whereas on the other hand, in slower-paced, more deeper and immersive gaming experiences that have graphics as much a feature as the gameplay such as say, Crysis or The Witcher 3 just to name a couple off the top of my head, higher gaming resolutions make more of a difference on the experience. In other words, it's more appreciated and worth it when compared to other games where you wouldn't notice the difference in graphical detail as much. Just something to think about when choosing the right resolution for your gaming PC.

VPN software is quite important in this day and age and will improve the security and privacy of your PC when online. There are also benefits to using VPNs for gaming.
There's lots of VPNs out there but the ones I recommend most to gamers is ExpressVPN (special link that gets you 3 months off. they also offer a free trial here) and NordVPN which are both highly rated gaming VPNs because they're the fastest and most secure.
Indie game dev currently working on my first public release after years of hobby projects, a story-driven VR FPS built with Unreal Engine (to be announced soon here for anyone into VR FPS's). Also likes writing about tech, which also helps fund development of the game.
My favs of all time are OOT, Perfect Dark, MGS1, MGS2, GE007, DKC2, THPS3, HL1, and HL2, with the most recent addition to my list of immortals being the VR masterpiece Alyx.
