3. Design & Build Quality

Look & Feel:
The G3 15 3590 has a relatively understated but “gamer-ish” design — not too flashy, which helps it double as a work or study machine. According to LaptopMag, its “racecar-esque” curves and slim bezel design give it a modern and sporty look. The chassis is mainly plastic, which is expected for its price range.

Build Materials:
While the plastic shell helps keep costs down, it’s not as premium feeling as more expensive gaming laptops. Some users report that the bottom panel and lid can flex somewhat, though the keyboard deck is decently rigid.

Thermal Design:
Heat management is a mixed bag. According to LaptopMedia’s review, the G3 3590 directs a lot of heat to the bottom corners of the lid — something that may not be a problem at first, but could become more noticeable over time with prolonged gaming. Several users on forums mention high temperatures, thermal throttling, and even the need to undervolt the CPU to control heat.

Keyboard & Input:
The keyboard is generally agreeable — comfortable for typing and gaming, though some note that arrow keys feel a bit small or cramped.The trackpad is large for a gaming laptop and responsive, though not necessarily a standout for precision work.

4. Display

Quality:
The G3 3590 offers a 15.6-inch Full HD screen. According to LaptopMedia, the color gamut is quite limited — the panel they tested covered only about 52% of sRGB, which is poor for color-accurate creative work.That means while the screen is fine for gaming and general use, it’s not ideal for graphic design, photo editing, or any workflow that requires accurate color reproduction.

Brightness & PWM:
LaptopMedia also noted that the panel uses aggressive PWM (pulse-width modulation) to control brightness, which could be uncomfortable for sensitive users. Many gaming laptops in this class make similar tradeoffs to reduce cost, but it's something to be aware of.

Refresh Rate:
Some SKUs have a 144 Hz panel, which is a strong point for gaming and helps make motion smoother, though not all configurations support it.

Viewing Angles:
Because budget panels are often used, viewing angles may not be as wide or stable as premium IPS displays, and color shifting might occur.

5. Performance

CPU & GPU Power:

With the Intel Core i5-9300H, the G3 3590 can handle gaming and productivity quite well. CPU performance is decent: NotebookCheck observed that the i5-9300H in this laptop could boost to 4.0 GHz for short bursts, though sustained loads lead to thermal balancing.
For users who choose the Core i7-9750H version, multi-threaded performance improves significantly — ideal for content creation or heavier multitasking.
On graphics, the GTX 1650 or GTX 1660 Ti Max-Q provide solid gaming performance. According to ItechGuides, storage and system responsiveness are good, and gaming performance generally meets expectations for the GPU class.

System Performance / Multitasking:
Thanks to dual RAM slots, it's easy to upgrade to a more capable setup (e.g., 16GB or 32GB), which improves multitasking. ItechGuides tested with 8 GB and noted that even with many browser tabs + YouTube playing, the laptop did not stutter.

Storage Performance:
In their review, ItechGuides reported strong SSD speeds for the G3 3590: in CrystalDiskMark, they measured very good sequential read/write performance for its NVMe drive.There's also a 2.5″ SATA bay for adding a larger HDD, which is great for gamers who want more game storage.

Gaming Performance:
Because of the combination of a decent CPU and Turing GPU, the G3 3590 can handle modern games at medium-to-high settings depending on the configuration. However, thermals and power limits can influence sustained performance. Some users on Reddit report thermal throttling, FPS drops, or uneven performance under load.Others solved some issues with undervolting or using Dell’s power-manager profiles.

6. Thermals and Noise

Temperatures:

In NotebookCheck’s stress testing, under combined CPU + GPU load (Prime95 + FurMark), the CPU ran at ~88–89 °C, while the GPU stayed around ~76 °C.
When gaming, they saw more moderate temps (~76°C CPU, ~72°C GPU) in their Witcher 3 test.
However, many real-world users speak of high heat:

“It is only issues regarding high temperatures … when I game reach around 80 °C–85 °C.”
"Massive frame drops … 100 C on my CPU … Thermal throttling happens after a few minutes."

Noise:
Because of the thermal load, the fans can get quite loud under gaming or stress. This is a common tradeoff for budget gaming laptops, where aggressive cooling is needed but the chassis isn’t particularly large or optimized for silent operation.

7. Battery Life

The G3 3590 typically comes with a 51 Wh battery. Based on testing by LaptopMedia:

Web surfing (real-world): ~6 hours 19 minutes with screen brightness at ~120 nits.
Video playback: about 5 hours 33 minutes (in their test conditions).
Under heavy gaming or load, battery life drops drastically (as expected).

This battery life is quite respectable for a gaming laptop, though if you’re gaming or running heavy workloads you’ll almost certainly need to be plugged in for consistent performance.

8. Upgradeability & Service

One of the strong points of the Dell G3 3590 is upgrade potential:

RAM: Two SO-DIMM slots, up to 32 GB DDR4.
Storage: M.2 slot for NVMe SSD + 2.5″ SATA bay for HDD or additional SSD.

This makes the G3 3590 a flexible device for future upgrading, giving more value over time.

9. Multimedia, Keyboard, and Sound

Keyboard:
The keyboard is decent for both gaming and typing. According to LaptopMedia, key travel and layout are comfortable, though the arrow keys are a little small. The keyboard deck does get some warmth under load, but it's not overly problematic.

Touchpad:
The touchpad is large and responsive, with decent tracking. It’s not a precision workstation-level touchpad, but good enough for most tasks.

Speakers / Audio:

According to NotebookCheck, the built-in speakers are “lacking in bass” and the palm rests might vibrate at higher volumes.
The laptop uses Nahimic 3D audio, giving some flexibility in sound profiles.
For gaming or media, headphones or external speakers are recommended for a better audio experience.
