Running a game and a live stream simultaneously means the system is handling two demanding workloads at once: rendering the game at high frame rates and encoding video for broadcast in real time. The machines below handle both jobs without the stream degrading gameplay performance, covering desktops and laptops for different budget levels and setups.

Custom Build: Ryzen 7 9800X3D + RTX 4080 — The Benchmark Dual-Use Setup
AMD’s Ryzen 7 9800X3D is the strongest gaming CPU available for simultaneous streaming because its 3D V-Cache reduces game CPU usage, leaving headroom for OBS encoding on separate cores. Paired with an RTX 4080, NVENC handles stream encoding without touching the CPU at all. 32 GB of DDR5 RAM is the standard build spec. This requires assembling the PC yourself or using a custom builder, but the performance ceiling is clear: 1440p or 4K gaming at high frame rates with a clean 1080p60 or 1440p60 stream running concurrently. No pre-built matches this configuration at this price point.
Asus ROG Strix G16 — Portable Streaming Station
The ROG Strix G16 packs an Intel Core i9-14900HX and RTX 4080 laptop GPU into a 16-inch chassis. The 16-inch QHD 240 Hz display is the primary gaming monitor, and OBS Studio handles streaming without measurable frame-rate loss thanks to NVENC encoding offloading from the CPU. The ROG Intelligent Cooling system keeps both CPU and GPU within operating temperature during extended streaming sessions. A Thunderbolt port supports a second external monitor, which is useful for managing OBS overlays and chat separately from the game. The machine weighs 2.5 kg, so it is portable but clearly a desk machine when streaming.
Lenovo Legion Tower 7i — Pre-Built Desktop That Ships Ready
The Legion Tower 7i with Core i9 and RTX 4070 Ti Super comes factory-configured and requires no assembly. Lenovo’s included Legion AI Engine manages performance profiles, and the tower chassis has strong airflow with a mesh front panel. OBS encoding via NVENC leaves CPU usage headroom well under 50% during typical gaming sessions. The tool-less side panel allows straightforward RAM and storage upgrades. Atcurrent pricing it costs more than building equivalent parts, but the warranty, support, and no-assembly convenience justify the premium for users who want a working streaming PC the same day it arrives.
MSI Raider GE68 HX — RTX 4070 Laptop for Portable Streams
The Raider GE68 HX uses an Intel Core i9-14900HX with an RTX 4070 laptop GPU, hitting the sweet spot of streaming capability without reaching RTX 4080 pricing. OBS at 1080p60 with NVENC runs without impacting gameplay at 1440p on this hardware. The 16-inch QHD 240 Hz display handles the visual demands of high-frame-rate gaming. The GE68 includes Wi-Fi 7, which supports the higher bitrates useful for higher-quality streams without a wired Ethernet connection. Thermal performance is solid with Cooler Boost 5 cooling and two-fan airflow.
Acer Predator Orion 5000 — Upgradeable Pre-Built Desktop
The Predator Orion 5000 ships with a Core i7 and RTX 4070, which handles 1080p streaming alongside gaming reliably. The case design gives priority to airflow with three 120mm front intakes and dedicated GPU cooling airflow channels. Acer leaves the PCIe slot and power supply with headroom for a future GPU upgrade. RAM is expandable to 64 GB. For streamers who want a capable starting point and expect to upgrade over a 3-year cycle, the Orion 5000 offers both current performance and future flexibility. Acer’s support includes a one-year warranty with on-site service upgrades available.
How to Choose a Computer for Streaming and Gaming
The GPU’s built-in hardware encoder (NVENC for NVIDIA, AMF for AMD) does the heavy lifting in modern streaming setups. Prioritize an RTX 40-series or RX 7000-series card at minimum. A CPU with high single-threaded performance and enough cores keeps the game running smoothly while background threads handle encoding and scene transitions in OBS.
16 GB of RAM is adequate; 32 GB is the safe choice for games that use over 8 GB. Storage speed matters for game load times and recording — an NVMe SSD is standard. If streaming from a laptop, ensure the power adapter is connected during streaming sessions to prevent thermal throttling from battery management.

Frequently asked questions
How much RAM do you need for gaming and streaming at the same time?+
16 GB of DDR5 RAM is the practical minimum for streaming and gaming simultaneously in 2026. OBS Studio typically uses 2 to 4 GB of RAM during encoding while a game is running. 32 GB provides more headroom for memory-intensive games and eliminates the risk of stuttering caused by RAM pressure during concurrent encoding and rendering.
Is it better to use a hardware encoder or software encoder for streaming?+
Hardware encoders like NVIDIA NVENC (RTX series) and AMD AMF produce good quality streams with minimal CPU overhead. NVENC on RTX 40-series cards is particularly efficient, freeing CPU cores for the game itself. Software encoding with x264 produces slightly better visual quality at the same bitrate but puts more load on the CPU, which can cause frame drops in CPU-intensive games.
