In a price range of under $1000-1350, the gaming desktop comes with a 9th-Generation 9700 Intel Core-i7 processor. Besides, the gaming desktop offers premium features like 16GB RAM, 6GB Nvidia GeForce GTX 1660 Ti Graphics card, 500 GB SSD.

Let me make one thing clear, the more specifications you want from your gaming desktop the more you have to invest in it. I mean to say, for more powerful features, like 1TB SSD, the NVIDIA GeForce RTX 2060 graphics card, Killer speedkiller Gigabit Ethernet, and a stunning cooling system for proper airflow you would have to go for higher priced edition.

Dell G5 Design

In terms of design, the G5 gaming tower offers whats it promises. Packed in simplicity the gaming tower is actually a perfect choice. Having a very low weight nearly 18.6 pounds, and medium-size in 14.5 x 12.1 x 6.7 inches dimensions the chassis is a big monster that offers blazing fast speed. Not only can you put it on the floor without any issues but also you can keep it on your gaming desk as it will not cover a huge space due to the compact size.

Overall, I really liked the chassis that looks pretty durable and easy to carry and manage. The plastic rectangle pattern combined with blue light helps to get a clear inside view of the tower.

On the front side, a blue LED strip in a diagonal pattern is most appealing. Sadly you can not change colors as this is not a customized RBG light that can be seen in most of the RBG gaming keyboards. The LED and rectangular openings let you monitor the hardware without opening the whole setup which is a nice modification.

Ports and Connectivity

What made me feel happy is that the Dell G5 gaming desktop comes with all ports necessary for the working of high-end desktops. Starting from the front side, the desktop has one 3.5mm mic jack, a 3.5mm audio jack, one USB-C port, and three USB-A ports. On its backside, you will find six USB-A ports.

In terms of connectivity you will get Bluetooth 4.2 connectivity, and Qualcomm DW1810 chip for 802.11ac wireless on the internal side. Besides, there is a DisplayPort, an HDMI port, a DVI port, and an Ethernet port.

One good thing about Dell G5 5090 desktop is that upgrading this tower is quite easy. Just remove screws from the backside and insert your required accessories in the desktop. As this is a prebuilt Gaming desktop, you will not add additional parts due to limited ports rather you may replace some of its parts like RAM or GPU.


In addition, the G5 5090 comes with a traditional mouse and keyboard. These accessories are not much appealing due to the cheap plastic build. For this purpose, you may find the best gaming keyboards or the best gaming mice here.

Productivity Performance

Usually the default G5 desktop comes with a 9th generation Core i7 processor fully loaded with features like 512GB SSD and 16GB RAM that boosts its speed for an ultra-fast gaming experience. Its speed when compared with its competitors like Skytech Blaze 2 and Nitro 50 earned it achieve a good ranking.

Through its SSD drives, you will be able to send massive 5GB files at an ultra-fast speed of 550 MBps. The desktop 4K to 1080p conversion speed is also the highest, which means you will be able to complete tasks in just a few minutes.

Dell G5 5090 – Gaming Performance

Actually, the G5 5090 model is 1080p optimized, which means you will get no problem playing high-definition games. In the gaming performance test, I enjoyed playing Tomb Raider, Star Wars, Street Fighter V, Far Cry New Dawn and Assassin’s Creed at 1080p with 60 frames per second. In each game, the desktop gave excellent frame rate performance (60-80 fps).

In every benchmark and performance analysis, the G5 5090 proved itself as an outstanding gaming desktop that is best for every gamer. Had you added the best gaming monitor in your accessories i am sure the results would definitely be beyond imagination.

In addition, the results with 4K were satisfactory, albeit not outshining as this desktop is 1080p optimized. No matter whether you are playing World of Warcraft, Overwatch, Thronebreaker: The Witcher Tales, or the Age of Empires II you will never feel disappointed after having this gaming desktop.

Dell G5 – Software

As you have read in its specifications that G5 5090 comes with pre-installed Dell Software Windows 10 Gome Edition. The software is user-friendly and easy to navigate. Plus you can get in touch with customer support service, update firmware and even optimize USB-C displays.

The good thing is that these features allow you to stay updated about firmware and software updates. The downside is that these features eat a lot of RAM and sometimes you will have to switch off unnecessary features to save RAM memory.

Another plus point of buying a desktop G5 desktop model is a one-year free service of McAfee Antivirus. Most of the McAfee users would find it a quite a perfect bonus, while others may switch to the required Antivirus based on personal preference. The reason is that McAfee Antivirus sometimes considers some of the important gaming files as trojans which is hectic and unwelcoming. You may choose the Windows 10 Default Defender program that works like a charm and does not create complications.

Is G5 5090 future-proof design?

Sadly the G5 tower has a pre-built compact design. As we have already discussed, you are getting a ready-made gaming desktop. That is to say, there will be limited options to further upgrade this gaming tower. You may , however, upgrade some of its options like RAM and GUPs which is a huge limitation. This is the basic reason that the 5090 model is not as future-proof model as the custom-made gaming desktops have to be.

What you may expect something good is a Standard one year warranty of parts. Additionally, you may get warranty upgrades up to 4 years depending upon your choice. You may, however, save more than $300 with Dell’s Premium upgrade plan beside accidental protection plan. This is actually a little bit more to lengthen its lifetime.

Alternatives to Dell G5 Tower

Some of the best gaming PCs alternatives to G5 5090, that we thought perfect for your choice are;

These pre-built PCs are the best alternatives for every serious gamer. You may choose any one of these depending on your needs and interests.

Bottom line

Overall, I really liked the Dell G5 gaming desktop. The 5090 offers a 1080p premium quality display. Though not equal to 4K displays, yet it still competes aggressively against every gaming desktop in terms of performance and quality. The user-friendly software, attractive chassis, and ultra-fast speed are perfect combo that appeals to every serious gamer.

The only downside is the lack of a dedicated 4K display and limited upgrading options that restricts its suitability for some gamers. Yet in a price range between $900-1300, this is the best option. For further information, you may also watch a video of the Dell G5 Gaming Desktop review.
