Advice on Building a High-End Gaming PC After 15 Years
Asked by
MellowOrbit42
I'm planning to build a gaming PC and would appreciate some guidance. I've assembled PCs before, but it has been more than 10 years, so I'm out of touch with current hardware and could use advice on whether my proposed parts make sense.
I mainly enjoy real-time strategy games, but I want the system to handle a wide range of modern games. My priorities are a full-size case, good sound dampening, RGB lighting, and enough performance to remain a strong gaming machine for at least four years.
I'm also unsure whether I should use air cooling or liquid cooling. I'd like to understand the differences in performance, noise, maintenance, reliability, and long-term value before deciding.

The build appears significantly over-specced in several areas. For gaming, the 7900X3D may not be the best choice compared with a gaming-focused X3D processor such as the 7800X3D or a newer equivalent. The motherboard also seems far more expensive than necessary, and a £500 case is difficult to justify unless you specifically need its features. Modern motherboard audio is usually sufficient, so a dedicated sound card is only worthwhile if you have particularly demanding audio equipment. A 1600W power supply is also unnecessary for this system; around 800–1000W should provide plenty of headroom.

There is also room to redirect some of the budget toward the graphics card and gaming-focused CPU. The selected memory does not need to be from a particular brand; compare speed, timings, capacity, and price instead. Unless you need an enormous amount of internal space or special workstation hardware, a large but more conventional case should still provide good airflow, RGB support, and reasonable noise control.

An 800W unit should be enough for this kind of build, while 1000W gives comfortable overhead. A 1200W model would only make sense for an unusual multi-GPU or heavily upgraded system, and 1600W is excessive for a build with roughly 600–650W of expected maximum draw. Choose a reputable, efficient model from a reliable power-supply tier list rather than paying for capacity you will not use.

If you are using high-end headphones or speakers, an external DAC and amplifier can be a better option than an internal sound card because they avoid electrical interference inside the PC. For ordinary gaming headsets or desktop speakers, the motherboard audio will generally be perfectly adequate.

For cooling, liquid cooling can offer slightly better temperatures and may be quieter with a high-end radiator, but the pump will eventually wear out and the system is more complicated. A good air cooler is cheaper, simpler, and can last for many years; usually the only part you replace is the fan. A Thermalright Phantom Spirit-class cooler should handle a powerful Ryzen processor well, although it may be somewhat louder under heavy load. You probably do not need to buy extra thermal paste either, since most coolers include enough.

MellowOrbit42: That makes sense. I was assuming an internal sound card was automatically the best option, but I’ll look into whether my headphones and speakers would actually benefit from a dedicated DAC.
