I'm planning to build a desktop and need some advice on how to allocate my budget across different components like the GPU, CPU, motherboard, and so on. I'm looking at various use cases such as programming, PCB design, simulation, gaming, and some everyday tasks. Any tips on percentage allocations for these components? Also, as a side question, how do you choose coolers and fans for your PC?

Start by choosing the CPU and GPU that fit your needs and then budget the rest around that. In general, for a gaming build, aim for about 40% of your budget on the GPU, 30% on the CPU, and the remaining 30% on other components. Just be cautious not to cheap out on the power supply – a good PSU is crucial.
For gaming performance, calculate what resolution and framerate you want; that’ll heavily influence your GPU choice. Once you know that, look into the best matching components. And don’t forget, while it’s tempting to go for higher-end parts, there’s often great value in mid-tier options that still deliver solid performance.
A good rule of thumb is to allocate around 50% of your budget to the GPU, especially if gaming is a priority. For coolers, I like options from Thermalright that are affordable yet highly effective. As for fans, choosing a case with pre-installed ones can save you money. And remember, if you're building it yourself, you'll generally get better quality components compared to purchasing a prebuilt system.
You should definitely make sure you understand your total budget based on what you can afford after other expenses. Then allocate 50-60% towards the GPU if gaming is a priority. If you're doing tasks like design or simulation, put more into the CPU. Finally, don’t skimp on cooling solutions; a decent air cooler or a budget-friendly AIO can go a long way.
It really depends on what you’re using the PC for. If it's mostly for gaming, focus more on the GPU. For workloads like running virtual machines, a stronger CPU is essential. I personally prioritize based on what I want from my system — like 1440p gaming or dual-booting Linux. Always match the CPU to your GPU to ensure balanced performance.
