Component Deep Dive
Why we selected each of these 8 parts for this build and how they fit into the compatibility ecosystem.
AMD Ryzen 5 7600
Recommended
The Ryzen 5 7600 serves as the ideal budget-conscious gateway to the AM5 platform, delivering excellent gaming performance without breaking the bank. Its 6-core, 12-thread configuration handles AV1 streaming encoding efficiently when paired with the GPU's hardware encoder. Operating at a modest 65W TDP, it keeps thermal output low while boosting up to 5.1 GHz to feed the RX 7700 XT at 1440p. Opting for this non-X variant saves crucial dollars for the GPU while securing a viable upgrade path to future Zen 5 or Zen 6 processors.
- Excellent gaming performance on the efficient AM5 platform
- Low 65W TDP keeps power draw and thermals easily manageable
- Guaranteed upgrade path to future AMD Ryzen CPU generations
- Slightly lower clock speeds than the 7600X variant
- Included Wraith Stealth cooler is loud under heavy loads

Crucial Classic 16GB (2 x 8GB) DDR5-5600 CL46
Recommended
Budget constraints dictate our memory choice, and this Crucial Classic 16GB kit provides the baseline DDR5 performance required by the AM5 platform. Operating at 5600 MHz, it ensures the Ryzen 5 7600 is not severely bottlenecked compared to older DDR4 systems. The dual-channel configuration is critical for maintaining smooth 1440p 1% low frame rates while streaming. While the CL46 latency is relatively high, this kit represents the most cost-effective way to get operational DDR5 memory into this sub-$700 build.
- Dual-channel configuration ensures optimal bandwidth for Ryzen CPUs
- Reliable Micron ICs offer stable plug-and-play performance
- Very affordable entry point into DDR5 system memory
- High CL46 latency limits absolute peak CPU performance

Thermalright Assassin X 120 Refined SE
Recommended
While the Ryzen 5 7600 includes a stock cooler, upgrading to the Thermalright Assassin X 120 Refined SE is highly recommended for a quiet streaming environment. This single-tower cooler features four direct-touch copper heatpipes and a 120mm PWM fan that keeps CPU temperatures well below thermal throttling limits. By keeping the CPU cooler, it allows the Ryzen chip to sustain its boost clocks longer during intensive streaming sessions. Its compact 148mm height guarantees easy clearance inside the Montech case without blocking the RAM slots.
- Outstanding cooling performance for an entry-level price point
- Much quieter than the stock AMD Wraith Stealth cooler
- Compact height ensures excellent case and RAM clearance
- Installation brackets can be slightly tedious to mount
- Thermal headroom is limited for higher TDP processors

Compatibility Notes
Socket, memory, power, and case fit should be verified against retailer specifications before purchase.
Upgrade Path
The AM5 platform offers an excellent upgrade path, allowing you to drop in future AMD Ryzen processors without replacing the motherboard. Upgrading to 32GB of faster DDR5-6000 CL30 memory will improve 1% low framerates and multitasking performance while streaming. Additionally, the 650W ATX 3.0 power supply can easily accommodate mid-range GPU upgrades, and the dual M.2 slots on the motherboard leave room for adding more high-speed NVMe storage down the line.
Tradeoffs
To hit the aggressive $700 price point, several compromises were made. The A620 motherboard lacks PCIe 5.0 support and has limited VRM heatsinks, which restricts heavy CPU overclocking. The 16GB DDR5 memory kit runs at a slower 5600MHz CL46 speed rather than the optimal 6000MHz CL30 sweet spot, slightly holding back CPU performance. Finally, the Kingston NV2 SSD is an entry-level QLC drive that may experience slower write speeds during massive file transfers, and the Thermaltake Smart BM3 is a Bronze-rated unit rather than Gold.
FAQ
Can this PC stream and play games at 1440p simultaneously?
Yes, the Radeon RX 7700 XT features a dedicated hardware AV1 encoder, which offloads the streaming workload from the CPU, allowing you to stream at 1440p with minimal impact on game performance.
Is 16GB of RAM enough for streaming in 2026?
While 16GB is sufficient for running most modern games alongside a streaming tool like OBS, upgrading to 32GB is highly recommended if you plan to run heavy background applications, overlays, or chat bots simultaneously.
Why choose an A620 motherboard instead of a B650?
The A620 chipset was chosen to keep the build under the $700 budget limit. While it lacks advanced overclocking features and has fewer PCIe lanes, it fully supports the Ryzen 5 7600 and DDR5 memory at stock speeds.
Does the CPU cooler fit inside the Montech case?
Yes, the Thermalright Assassin X 120 Refined SE has a height of 148mm, which easily fits within the Montech AIR 100 LITE's maximum CPU cooler clearance of 160mm.
