The most important specifications in a gaming PC are the graphics card, storage, and power supply. Since they are all directly dependent on each other, the more powerful graphics card you have, the better power supply and storage it will require to keep the PC and games running smoothly. We are writing this in 2025, and a powerful graphics card such as this one:
NVIDIA GeForce RTX 3090 Ti (24 GB GDDR6X)
can deliver high-quality graphics in almost all types of modern 3D games. You can find (16, 12 & 8) GB in the AMD Radeon RX & GeForce. They are equally good at delivering the best performance.
CPU
Not only the GPU, CPU also has equal importance. You need to look for high clock speed, such as 4.0 GHz or even above, processors. Multicore processors handle gaming and streaming at the same time. If you are building your own gaming PC, then look for the latest generation Intel® Core™ i7/i9 or AMD Ryzen™ 7/9 processors. These can easily deal with performance-hungry and intensive tasks. Low on budget can look for AMD Ryzen 5/7 or Intel Core i5/i7
RAM
Now comes the RAM. It has only one formula, the more the better. Look for 32 GB o,r if your pocket money is finishing, then 16 GB is recommended for 3D gaming. Futuring-proofing can sometimes break the bank, so divide your money accordingly. Crucial or Samsung should be your choice.
Storage
Games are quite heavy in terms of storage capacity. Storage can be anywhere between 1TB to 8 TB. Make sure they are SSDs. Our recommendation is Samsung NVMe M.2 SSD (PCIe Gen 4)
Try to stay away from HDDs and below 1 TB storage. Half of the storage is consumed by the operating system and updates. So, 500 GB would not be ideal.
Cooling System
The best cooling systems are liquid cooling. Airflow design is equally important, so the system can breathe in and out easily. This can prevent overheating and keep the CPU and GPU cooler for stable and steady performance. Longer gaming sessions can sometimes heat up the CPU. If the fans are large enough and have enough airflow, then they give the peak performance in longer competitive gaming sessions. Our recommendation:
Motherboard
It is always challenging to select the right motherboard, which has the necessary slots and ports and can be upgraded in the future, and the case has enough room so that larger graphics cards can easily reside. Our recommendation would be ASUS, as they have the industrial top-quality motherboards such as this one:
Case
You may like many cases, some may attract you more due to the perfect ambient lighting, but the best one will be with better airflow and adjustable for all the PC components. Only look for a case that has better ventilation.
Display
If you already have a 4K OLED from Samsung, LG, or even Philips, then you may not need any display. However, if you are ready to invest, look for a display with OLED and a minimum of 144Hz, which will serve you well for many years to come. 240 Hz is available in Dell, Asus, Samsung, Acer, Alienware, and INNOCN. Our recommendation is:
Budget
You will have two options when it comes to allocating a budget for the gaming PC. Many of us will try to save by considering pre-built options, as they are economical, but they will not give you peak performance. Custom-built can future-proof, but they are more expensive in terms of price.
Brand & Warranty
Top brands such as HP, Dell, Acer, ASUS, Corsair, ROB, and Lenovo are all recognized in the field of gaming PC. They are reliable and provide the best support as well as warranties. For these brands, you may not need to read many reviews, but for newer brands, you need to read and research.
After reading this article, you will be in a position to choose a gaming PC that gives you the best performance within your budget.
