Buying a Gaming Mouse

Do you need a gaming mouse? The answer varies because not everyone wants the same experience and is willing to sacrifice the budget. Gaming mice are known for their performance, especially sensors, because they are designed to be low in latency. Gaming mice are also stylish and more handsome than typical office mice if you are someone who cares about aesthetics. In addition, gaming mice often have more features than standard mice, such as extensive programmable buttons, adjustable DPI/CPI range, and other personalization through the mouse or its software.

About Corsair Dark Core RGB Pro and Logitech G903

Which gaming mouse is the best? There is no solid answer because everyone has their preferences. One of the crucial factors when choosing any mouse is ergonomics, which is highly subjective depending on your hand size and grip style. You can find the best gaming mouse for your hand and application by considering ergonomics and features. You can also buy from reputable names like Corsair and Logitech to save time. These companies carry lots of different gaming peripherals at different budget ranges and with varying features.

The Corsair Dark Core RGB Pro and Logitech G903 are perfect options for everyone who wants a reliable mouse but are still versatile for FPS and MMO games. These mice are expensive, and if you want something more affordable but still work impressively, the Razer Orochi V2 Vs Viper Ultimate are excellent alternatives. The main difference between these mice is ergonomic because they have different shapes that affect comfort and user types. Like Viper Ultimate, the G903 is an ambidextrous mouse with thumb buttons on both sides.

The Logitech G903 is one of the most versatile and comfortable gaming mice because it conforms to both left and right hands. The sensor performance is fantastic, and you have many programmable inputs. The only issue we have with G903 is the price because it is pretty expensive. The Dark Core RGB is slightly cheaper with superb performance if you are a right-hand user and don’t care for extensive programmable inputs.

Corsair Dark Core RGB Pro and Logitech G903 Design

The mouse’s shape decides ergonomics and who can use the device. The Dark Core RGB Pro has a right-hand form with a flare to support the thumb and side buttons on the left side. This mouse has a textured finish for grip and measures 127mm long, 81mm wide, 43mm tall, and has a grip width of around 54mm. On the other hand, the G903 has a true ambidextrous/symmetrical shape that looks like an alien’s head from above. This mouse has a soft matte coating, measures around 130mm long, 65mm wide, and 40mm tall, and has a grip width of 61mm.

Corsair Dark Core RGB Pro and Logitech G903 Ergonomic

Ergonomic or comfort is subjective because we may hold the mouse differently and have different hand sizes. The Dark Core RGB Pro is an excellent mouse for comfort because it feels great with a palm grip regardless of hand size and is still awesome with a claw grip unless you have small hands. This mouse is still easy with a fingertip grip if you have large or extra-large hands. As for the G903, this mouse is fantastic and versatile whether you want a palm or claw grip, regardless of hand size.

Surprisingly, this mouse is still comfortable with a fingertip grip for users with medium to extra-large hands. Similarly, those with small hands might find a few buttons at the front difficult to reach and press due to the length. Another G903’s biggest advantage over dark Core is the shape because it is truly ambidextrous, meaning you can hold it with your right or left hand, and the mouse will feel the same.

Corsair Dark Core RGB Pro and Logitech G903 Buttons

We also want to see the buttons on Corsair Dark Core RGB Pro and Logitech G903 because most people want programmable buttons for convenience. The Dark Core RGB Pro has eight buttons, including two side buttons, giving you eight programmable inputs because you can reprogram all of them. The G903 has thirteen buttons with two buttons on each side, giving you 21 programmable inputs. A surprising feature of this mouse is the removable side buttons, giving you more freedom and better comfort with your right or left hand.

Another difference is on the scroll wheel because the G903 also tilts to the left and right. Both scroll wheels are notched and comfortable, but this tilting function makes the mouse more versatile for navigating large pages. As for the buttons, these mice are quiet with a soft click.

Corsair Dark Core RGB Pro and Logitech G903 Performance

Lastly, we want to see the Corsair Dark Core RGB Pro and Logitech G903 performance. Corsair gives Dark Core RGB Pro PixArt PAW3392 optical sensor with DPI/CPI range from 100 to 18,000 and adjustable in 1 DPI/CPI for best accuracy; this sensor has a lift-off distance of 2.4mm. On the other hand, Logitech gives G903 the PixArt PMW3366 optical sensor with DPI/CPI range from 50 to 12,000, adjustable in every 50 increments, and lift-off distance at 1.2mm. Performance is equally impressive, but unlike G903, the Dark Core also works with Bluetooth.

Corsair Dark Core RGB Pro Vs Logitech G903

The Corsair Dark Core RGB Pro and Logitech G903 are good gaming mice with high performance and ergonomics. The main difference between the two is ergonomic and programmable buttons because the G903 has a more versatile shape and size while maintaining its ambidextrous design. The Dark Core is still a comfortable mouse but less versatile, especially for left-hand users. But, this mouse has a wider DPI/CPI range while G903 wins on the programmable inputs and customization.

The decision is yours because we may have different preferences. We recommend the Dark Core RGB Pro because it has good comfort, performs impressively, and is cheaper. But, the G903 is a solid choice if you are a left-hand user and want more programmable inputs or prefer a lighter wireless mouse because the Dark Core is noticeably heavier.
