As a PC gamer you definitely need some tools of the trade apart from your own computer. Some of the products I’m about to suggest are mostly aesthetical and not particularly essential for your daily life, while there also are a bunch of very useful accessories you may need for your physical comfort (extremely important if you generally spend many hours at your desk) and a better gaming performance in general.
Sound related we of course have the headsets. Among my choices you’ll find HyperX Cloud Stringer Gaming and Wired Cat Ear Headphones. The latter seems to be quite popular in Japan and among all the cat lovers who also have a weakness for colorful bright lights in the darkness.
If you need to replace your keyboard or mouse but also want some style and visual effect, I highly recommend PICTEK Gaming Mouse Wired and Razer Cynosa Chroma. If you want to stay more sober and do not enjoy the flashing lights at all, you will probably appreciate something like Tecknet Kraken 3 LED Adjustable Backlit instead, which has the typical gaming keys highlighted in red.
For the controller you can easily use your Xbox or Playstation one(s), but in case you don’t play on console at all you can get the original Microsoft and Sony ones either way or use a Steam controller if you mainly have Steam titles. Usually the non original controllers may suffer of a lack of quick input compared to the official ones, but I personally still use a $8 one on PC most of the time (even if I can use the PS3 and 4 controllers) with no troubles at all.
This is probably something not many people are aware of, but the monitor can affect your gaming performance as well. Apart from the clear image a high quality screen could offer, the more powerful it is the better your Refresh Rate will be. The Refresh Rate, or Vertical Scan Rate, is the number of times in a second that a display hardware updates its buffer. Nowadays the standard default Refresh Rate should be 60Hz, but the highest values can go up to 240Hz like the ViewSonic XG2530 25″. LG 32UD59-B 32-Inch 4K UHD LED-Lit Monitor offers a 4k resolution (3840 x 2160), but depending on your needs you can pick a less expensive screen like Acer G236HL Bbd 23-Inch Screen LED-Lit.
Before buying a 4k monitor though, you also have to consider that if your resolution is particularly high, the overall text and icons will appear way smaller than a standard 720p or 1080p. If you have sight issues and tend to move your face closer to the screen while reading something a bit too small for your own good, the 4k resolution is something you should only use for a TV (unless you plan to take high quality screenshots and videos while decreasing the resolution to 1920×1080 during a normal usage).
In case you need some mount stands, Jestik Arc Triple Monitor Stand is perfect if you plan to play your games on multiple screens. Alternatively, Cable Matters Height Adjustable Single Monitor Mount is a good option, which also includes a 4k HDMI cable.
Now, after all these good looking products, it’s time for me to give you a suggestion regarding your welfare. If you play a lot with mouse and keyboard without some proper precautions you may be potentially exposed to the well known carpal tunnel inflammation. I recently got it myself because apart from playing, I spend a lot of time on my PC for work. Non only that may give you common pains and sleeping/tingling nerves along your hand, wrist and even arm up to the elbow, but carpal tunnel will most likealy require surgery in order to go back to normal if it’s not treated properly. As much as we love playing we cannot forget about our health and comfort, reason why I recommend a mouse and keyboard rest. Gimars Superfine Fibre Soft Memory Foam Gel includes both into the same package.
We also want to be extremely comfortable while sitting and keep our back in a correct position. Spending too much time on a chair can already be painful enough, but if we have an inappropriate posture that can seriously damage our back and also cause cervical pains (yes, I talk from experience). For a good gaming life I suggest something like the Furmax Gaming Chair.
