Building a PC: Choosing the right keyboard

Categories: Tech | Pubby Cash Received:  0

The whole point of building that gaming PC was so you can effortlessly game using a mechanical keyboard. But which one should one buy? Razer makes good keyboards. Mechanical switches have always been superior for speed and accuracy, and before 2010, they were only used for typing – because they were made precisely for that purpose. Razer then made the radical decision to use mechanical switches for a gaming keyboard, and that birthed the world’s very first gaming mechanical keyboard, the Razer BlackWidow. Four years later, Razer redefined the limits of gaming performance by creating mechanical switches that were designed specifically to meet the demands of gaming - the Razer Mechanical Switch was born. You can find various switches out there, each marked with their unique feel and color. Razer has three distinct switches, notably the green, orange, and yellow. When you buy a Razer keyboard, you can choose which style you want. But the question now is which one do you want? The first type is the green switch. It can be classified as the classic. It's for those who want to feel and hear every keypress, the Razer Green Mechanical Switch features a tactile bump and distinctive click sound along with optimized actuation and resets points for best in class gaming and typing performance. Some people are confused with the term "tactile" when it comes to mechanical switches, but it's nothing more than that satisfying click each time your finger strikes a key. It's that button-like feeling. Next, we have the orange key. Silent, but deadly. the Razer Orange Mechanical Switch is for those who enjoy a tactile bump and feedback without the audible click. Enjoy the same optimized performance with less actuation force as a Razer Green Mechanical Switch, while maintaining a quiet gaming experience. For most people, the orange keys are the way to go. Finally, we have the yellow switches. You are looking at the fastest and quietest switch. Best for rapid-fire keypresses and fast-paced gaming, the Razer Yellow Mechanical Switch has an ultra-fast actuation of only 1.2mm, which allows you to press keys multiple times as fast as possible. There's some tactile feeling, but not much, as the keys sink when pressed. If you don't like the button-like feeling in the keyboards, you should get the yellow switches. ...  Read more

Building a PC: Air or Liquid Cooling?

Categories: Tech | Pubby Cash Received:  0

Regardless of your build, cooling is always a must. I say that because, without proper heat management, your PC will be a furnace. It might overheat or blow up. It is especially important to select a cooler for your CPU because it is the hottest component in your computer. So when selecting a cooler for your processor, you have two options—air cooling and liquid cooling. Both have their advantages and disadvantages. Most CPU’s bundle a CPU fan that comes free with your purchase. While this type of cooling is satisfactory for casual PC users, gamers often upgrade to aftermarket air coolers that provide higher cooling efficiency. For most gamers, an aftermarket air cooler will provide more than enough power to keep their CPU running at optimal temperatures. Air cooling is also relatively safe. As opposed to liquid cooling, it is OK if the fan breaks during use because there aren't any electronic-threatening substances within the device. However, water is present in liquid cooling and water can damage electronics. Although air cooling might be satisfactory for your needs, you'll also need to consider the noise from the fans. The fans can get pretty noisy at times, especially when you're doing many tasks at once. If you can't stand the buzz of the fans, then maybe you should settle for liquid cooling. Practically silent, you can focus on what you want and not get any of the distractions. Liquid cooling is the best way to cool a CPU because water transfers heat much more efficiently than air. However, liquid cooling a PC can also be dangerous if water leaks onto hardware. Both air coolers and liquid coolers provide increased cooling performance over a stock CPU cooler. However, the cooling solution you decide to use inside your PC build will usually depend on a variety of different factors to go alongside performance. Air cooling offers a safe, reliable, but noisy cooling experience while liquid cooling is more efficient but could damage your parts. Overall, I'd have to go with liquid cooling because it's silent and powerful. Also, if I get a quality one, I shouldn't worry about any broken tubes whatsoever....  Read more

Building a PC: Choosing the Right Monitor

Categories: Tech | Pubby Cash Received:  0

When it comes to gaming, you need a good monitor. Without a monitor, you can't see what you're doing. The first step in choosing your monitor is to figure out the type. There are three main types: twisted nematic (TN), in-plane switching (IPS), and vertical alignment (VA). The names relate to the alignment of molecules within the LCD (liquid crystal display), and how they change when voltage is applied. All LCD monitors change the alignment of these molecules to work, but how they do so can drastically affect the image and response time. Each panel type has advantages and disadvantages. The easiest way to choose between them is to decide which attributes are most important to you. This largely depends on what you use your computer for, and how much you have to spend.

TN Panels:
While newer panels are always better than their predecessors, TN display technology still suffers from some notable drawbacks. One is its limited viewing angles, particularly on the vertical axis. It’s not unusual for a TN panel’s colors to invert completely when you view it from an extreme angle. Its color reproduction also isn’t that strong either. Most TN panels are incapable of displaying 24-bit true color and, instead, rely on interpolation to simulate the correct shades. This can result in visible color banding, and inferior contrast ratios when compared with IPS or VA panels. There are better options than TN displays.

IPS Panels:
IPS technology was developed to improve upon the limitations of TN panels—most notably, the poor color reproduction and limited viewing angles. IPS panels have vastly superior viewing angles than TN. Additionally, IPS panels are also known for their relatively good black reproduction, which helps eliminate the “washed out” look you get with TN panels. However, IPS panels fall short of the excellent contrast ratios you’ll find on VAs.

VA Panels:
Last but not least, we have the VA panels, which are something of a compromise between TN and IPS. They offer the best contrast ratios, which is why TV manufacturers use them extensively. VAs have slower response times than TNs and the newer Nano IPS panels with their one-millisecond response rates. VA monitors can come with high refresh rates (240 Hz), but this latency can result in more ghosting and motion blur. If you're looking for competitive gaming, try to avoid VA panels.

Now that you've decided which type of monitor to buy, you will need to figure out if that model will be compatible with your graphics card. With the GeForce RTX 2070, you will play at 144 FPS at high settings, and the GeForce RTX 2080 Ti will put you up at 200 FPS. The RTX 2070 can do 1440p at 144 Hz right now. However, at 1080p, you should consistently get 100+ FPS in any well-optimized game. If your monitor's refresh rate is lower than that of your graphics card, you will not get the full power of the graphics card.

Building a PC: Choosing the Graphics Card

Categories: Tech | Pubby Cash Received:  0

Ask any gamer what the most important component for a PC build is, and they would reply with the graphics card. After all, seeing is believing, and without good graphics, no matter how good your processor or monitor is, most gamers will experience something that haunts them in their sleep: LAG. What can trigger you more when you are doing well in a match when the screen suddenly freezes and you die? Now that you've understood that having a good graphics card is important, it is time to get into the research. Fortunately, I have already done that, and here's what I found. Nvidia makes great graphics cards. But why are they so great? They have ray-tracing technology which is performed by the RT cores to produce reflections, refractions, and shadows to make everything more realistic. Additionally, Tensor cores are used to fill in the blanks of partially rendered images as well as increasing the resolution of images. Some cards also have Deep Learning Super Sampling (DDLS), which boosts frame rates in games with graphically intensive workloads. Now you can game at the highest graphical settings and not worry about LAG. Though the best card is the Nvidia GeForce RTX 2080 Ti, I don't think it would be worth it to spend so much money unless you need the 4k resolution. So then we move down to the RTX 2070 series, which includes Gaming, Armor, Aero, Duke, and Sea Hawk sub-series. If you want the best performance, then go with the Gaming here. A good choice would be the Gaming Z. But it only has two fans. Aren't three fans better than two? That is the case if you want better cooling, but sometimes you would be better off getting two large fans versus three small fans because it makes less noise and is easier to replace. Also, the boost is very important as it will greatly impact your gaming experience. For example, the MSI Gaming GeForce RTX 2070 Tri Frozr boasts of three fans but has a boost clock of 1620 MHz whereas the dual-fan Gaming Z has a boost of 1830 MHz, which is faster. No wonder why the latter is almost twice the price of the former. So here's the bottom line, when choosing a graphics card, don't go for the one-fanned because they heat up too quickly. But stick to Nvidia's cards as they continue to exceed the standards of competitive gaming. Also, get the RTX over the GTX and opt for the 2000 series over 1000 because it's newer. Look for the advanced features such as ray-tracing and VR-ready. You won't regret it....  Read more
