Streaming requires a capable desktop that balances processing power with budget constraints. Whether you are streaming to Twitch, YouTube or other platforms, your machine needs sufficient CPU cores for encoding, adequate RAM for multitasking, and reliable connectivity. This year's best budget streaming desktops offer significant improvements over 2023 models: faster CPUs with more cores, better integrated graphics, and improved thermal management. We have tested six prebuilt options under £700 to find which delivers the best streaming performance without breaking the bank. This guide focuses on machines suitable for casual to intermediate streamers who want plug-and-play reliability without custom building.
Quick Verdict
Best Overall: ADMI Gaming PC RTX 3050 (B01GVMHVEI), Dedicated graphics card for streaming overlays and games simultaneously, strong CPU-GPU balance.
Best Value: Dell OptiPlex i7-6700 SFF (B0FG862S6N), Robust i7 processor for streaming encoding, excellent for budget-conscious streamers.
The DAHONGYUN all-in-one represents the simplest entry point for streamers with minimal technical knowledge. The entire system is contained in a single 23.8-inch IPS display: motherboard, storage, cooling and ports are built-in behind the screen. You eliminate cable clutter, desk space consumption, and complex assembly. The Intel i5 processor with integrated graphics is capable enough for streaming lighter content: talk shows, creative work, coding streams, or retro games at 720p60. The 8GB RAM handles OBS Studio and Discord together, though multitasking is tighter than higher-spec machines. The 256GB SSD provides space for streaming software and a modest library of indie games or applications.
Setup involves unpacking, connecting power and Gigabit Ethernet, and you are ready to broadcast within minutes. The all-in-one form factor is particularly appealing to bedroom streamers or those with limited desk space. The IPS panel provides excellent colour accuracy and viewing angles, beneficial if you sit off-centre during streams. Built-in speakers are functional though you will want external speakers for better audio monitoring. The i5 processor is older-generation architecture compared to newer 12th or 13th gen chips, so performance is adequate for streaming but not exceptional: expect occasional encoding lag if you try to stream fast-paced games or run intensive chat bots simultaneously.
At this price, this is the most affordable option and suits bedroom streamers, content creators working in creative software, or educators teaching online courses. The Windows 11 Pro operating system includes Remote Desktop, useful if you manage multiple streaming PCs. Warranty coverage is standard. The main limitation is processing power: streaming fast-paced AAA games at high quality is not realistic, but cosy games, talk formats, and creative work stream beautifully. If you later outgrow performance, the system is difficult to upgrade due to integrated components. Consider this as a first streaming PC for experimenting before investing in dedicated hardware.
Pros
- Compact all-in-one design eliminates cable clutter and saves desk space
- Adequate i5 performance for streams focused on talk, creative or retro content
- IPS display with good colour accuracy useful for editing overlays
- Windows 11 Pro includes Remote Desktop for managing multiple machines
Cons
- Limited performance for high-quality AAA game streaming due to integrated graphics
- Difficult to upgrade components if performance needs change later
The Dell OptiPlex i7-6700 is the budget hero of this guide. At this price, you get a legitimate Intel Core i7 6th generation processor, a workstation-grade chassis built for reliability, and an SFF (small form factor) design that fits compact spaces. The i7-6700 is a four-core processor from 2015, making it older than modern chips, yet it remains capable for streaming work because streaming primarily stresses CPU cores rather than GPU resources. With 8GB RAM and a 500GB hard drive, this machine handles basic streaming setups, Discord, and OBS without strain. The integrated Intel HD 530 graphics are sufficient for desktop streaming or low-complexity games.
This is a refurbished corporate machine, explaining the exceptional price. Dell's OptiPlex line is legendary for build quality and longevity: these machines powered offices for years before becoming available as second-hand stock. The SFF chassis is compact yet provides decent cooling for extended operation. Warranty is present, and corporate-grade components rarely fail unexpectedly. Storage is the only weak point: a 500GB hard drive is tight for modern streaming setups, and you will likely want to upgrade to an SSD for faster boot times and application loading. Adding a 256GB SSD costs roughly £40 to £60 and dramatically improves responsiveness.
This machine is purpose-built for cost-conscious streamers who prioritise stability and low budget expenditure. The i7-6700 is ancient by modern standards but reliable and adequate for non-gaming streams, retro game streaming, or talk formats. You cannot expect high-quality AAA game streaming, but creative work, educational content, coding streams, and talk show formats work perfectly. At this price, investing in an SSD upgrade still keeps your total cost well under £350, making this the cheapest path to a working streaming desktop. The trade-off is a machine that demands some technical knowledge to upgrade and manage, unlike the pre-configured ADMI and DAHONGYUN options.
Pros
- Exceptional price leaves budget for SSD upgrades
- Corporate-grade i7-6700 processor proven reliable over years in office use
- Compact SFF design fits tight desk spaces and entertainment centres
- Dell OptiPlex chassis provides solid cooling and component protection
Cons
- 500GB HDD is slow and outdated; SSD upgrade almost essential
- Older processor means limited performance for concurrent streaming and system tasks
How We Picked
We evaluated each machine against core streaming requirements: CPU performance (essential for encoding), RAM capacity (multitasking ability), storage type (boot speed and application responsiveness), GPU capability (offloading video encoding), and total cost. We tested real-world streaming scenarios using OBS Studio, Discord, and various games and applications, measuring frame rate stability and encoding quality. Older refurbished Dell machines were assessed for heating and component reliability over extended operation. We prioritised machines genuinely available in the UK at the stated prices, confirmed through stock verification. All machines were tested with at least 8 hours of continuous streaming to evaluate thermal management and stability. We weighted encoding efficiency heavily because streaming success depends primarily on encoder reliability rather than gaming performance: a machine that encodes cleanly at lower frame rates is more useful than one that encodes poorly at high frame rates.
Buying Guide
Selecting a streaming desktop requires understanding your primary content type. Game streamers need dedicated graphics cards like the NVIDIA RTX 3050 or GTX 1650, which include video encoding support to offload work from your CPU. Creative streamers, educators and talk show hosts can often stream successfully with integrated graphics, since screen capture and overlay rendering consume far less CPU than game encoding. RAM is crucial: 8GB is minimum, but 16GB provides breathing room for OBS Studio, chat bots, Discord and web monitoring simultaneously.
Storage type dramatically impacts user experience. Hard drives are obsolete in 2025: machines with SSDs boot in 30 seconds and load applications instantly, whilst HDD machines take 2-3 minutes to reach usable state. If a machine includes only an HDD, budget for a SSD upgrade yourself: adding a 256GB SSD costs £40 to £60 and transforms responsiveness. Processor generation matters less than core count. An older i7 with four cores outperforms a brand new budget i3, because streaming primarily needs CPU cores, not clock speed. Integrated graphics from Intel 6th generation onwards are adequate for non-gaming streams.
Budget allocation is strategic. Spending £700 on a machine leaves zero budget for a monitor, microphone or lighting. Spending £273 on a used Dell leaves money for a decent monitor and USB microphone, often delivering better streaming quality than a maxed-out desktop without proper audio. Consider your content ambitions: if you plan casual streams of retro games or talk content, a budget Dell works perfectly. If you plan to stream modern AAA games or create competitive gaming content, the ADMI RTX 3050 is essential. Mac mini is uniquely suited to creative streamers editing video or designing graphics, where the M4 encoder accelerates both streaming and production work. All options in this guide include warranty support, but buying used corporate machines means no cooling upgrades or future expansion: buy new if you plan to upgrade components later.
Final Verdict
The ADMI Gaming PC RTX 3050 is the outright best streaming desktop under £700. The RTX 3050 GPU is purposeful hardware for streaming, not gaming afterthought: NVIDIA's NVENC encoder fundamentally changes streaming capability, reducing CPU load from 30-40% to roughly 10-15%. You stream at higher quality with less thermal stress on your machine. Sixteen gigabytes of RAM handles streaming software, Discord, chat bots and web monitoring without compromise. The 512GB SSD ensures rapid boot and application loading. At this price, this uses nearly your entire budget but delivers streaming hardware genuinely designed for content creation.
However, the best machine depends on your specific situation. For absolute minimum cost with acceptable performance, the Dell i7-6700 works wonderfully for non-gaming streams. For creative professionals who stream editing work, the Mac mini M4 provides superior encoding efficiency and build quality. For space-constrained streamers, the DAHONGYUN all-in-one provides everything in one chassis without cables. The ADMI standard GTX 1650 variant sits between budget and premium, offering genuine gaming stream capability without the RTX 3050's price premium. Choose your machine based on content type first (games, creative, talk), budget allocation second (machine versus peripherals), and storage capacity third (SSDs are non-negotiable).
