A machine for gaming and streaming on one system. The key decision is about encoding, and it is less demanding than it used to be.
Encoding is not the problem it was
Streaming used to need a second machine or a large core count, because encoding on the processor competed directly with the game.
Modern graphics cards include dedicated encoding hardware that runs independently of the rendering units. Encoding on the card costs a small amount of performance, typically a few percent, rather than the substantial hit of processor-based encoding.
So a single-machine setup is now entirely reasonable, and the build looks much like a gaming build with more memory.
| Component | Part | Why this one |
|---|---|---|
| Processor | AMD Ryzen 7 7800X3D or Intel Core i5-14600K | Either works. The Intel part offers more cores for the background applications a stream involves; the AMD part is stronger in the games themselves. |
| Motherboard | B650 or B760 ATX with 2.5 Gigabit ethernet | Wired networking matters for streaming stability far more than for gaming. Prefer ethernet over Wi-Fi for the upload. |
| Memory | 32 GB DDR5 (2 × 16 GB) | This is the component to increase for streaming. Encoding software, the game, a browser full of dashboards and chat overlays add up quickly. |
| Graphics card | RTX 4070 SUPER class | Modern NVIDIA encoders produce good quality at modest bitrates. AMD cards encode well too; check current encoder quality for the specific generation. |
| Storage | 2 TB NVMe SSD | Local recordings are large. If you keep recordings for editing, plan a second drive using our storage planner. |
| Power supply | 750 W 80 PLUS Gold | Sustained load for hours at a time, which is why the efficiency and build quality matter more here than in an intermittently used machine. |
| Case | Mid tower with strong airflow | Streaming means sustained load rather than bursts. Airflow matters more than in a machine that idles between sessions. |
| CPU cooler | 240 mm liquid or a dual-tower air cooler | Sustained load again. Size for continuous operation rather than for peaks. |
What matters beyond the parts
Upload bandwidth is frequently the real constraint. Check what your connection actually provides before choosing a bitrate; no amount of hardware compensates for insufficient upload.
Use the graphics card encoder rather than the processor unless you have a specific reason not to. The quality difference at typical streaming bitrates is small and the performance difference is not.
A capture card is unnecessary for a single-machine setup. They exist for capturing from a separate machine or a console.
How this build was put together
Every component here was selected to serve the stated purpose at the stated budget, and the complete list was run through our compatibility engine before publication: socket, memory generation and slot count, case clearance for the card and cooler, power connectors and supply capacity.
We have not benchmarked these parts ourselves. The reasoning is based on published specifications, standards documentation, and practical experience assembling machines. Where performance figures matter to your decision, publications that run controlled tests are the right source. Our methodology page sets out how we work in full.
