Best $4,000 Gaming PC Build for 2026 (Streaming + 4K)

What $4,000 Gets You in 2026

At $4,000, you’re building the ultimate streaming and 4K gaming powerhouse. This tier adds dual RTX 4090 configurations optimized for streaming (one for gaming, one for encoding), professional-grade cooling loops, maximum storage (24TB), and enthusiast-grade everything. You’re not just playing games at 4K—you’re streaming them simultaneously at 4K quality to Twitch, YouTube, or professional platforms while maintaining 100+ FPS on your local display. This is the tier for professional full-time streamers, Twitch partners, and content creators who want absolute best-in-class performance.

The budget spreads across dual GPUs, dual cooling loops, massive storage, and power delivery that accommodates extreme workloads. You’re building a professional streaming studio that happens to be a gaming PC.

Target Performance & Resolution

4K gaming at 100+ FPS locally while streaming 4K simultaneously. Baldur’s Gate 3 runs 120+ FPS on your display while streaming 4K 60 FPS to Twitch without frame drops. Cyberpunk 2077 maintains 100+ FPS locally with full ray tracing while encoding a professional 4K stream. Alan Wake 2 hits 110+ FPS locally with 4K streaming active. You’re not making compromises—local gaming and remote streaming both run at premium quality simultaneously.

This is the tier where content creation and gaming stop being competing interests. Both happen at the highest level, in parallel, without performance degradation.

TOTAL | ~$4,000 | ±$300

GPU Choice & Why

Dual RTX 4090: one Kingpin edition for gaming ($1,800–2,200) and one standard RTX 4090 ($1,200–1,400) dedicated to streaming/encoding. Modern streaming software (OBS with NVENC) can use dedicated GPU encoding, offloading that work from your gaming GPU entirely. This setup provides complete separation: gaming GPU runs games at 100+ FPS, streaming GPU handles encoding without impacting gameplay. This is the professional streaming setup.

Dual RTX 4090 also enables professional rendering (3D workloads) and AI inference simultaneously with gaming. You’re building a multi-workload powerhouse.

CPU Choice & Why

AMD Ryzen Threadripper 9980X (32 cores/64 threads) is the ultimate content creation CPU. It handles 4K streaming encoding, game processing, video editing, 3D rendering, and multitasking at professional scale. 32 cores means you can dedicate cores to different workloads: gaming thread pool, streaming/encoding thread pool, background rendering—all simultaneously without contention.

This CPU scales to professional workloads while gaming beautifully. If you’re a full-time streamer or content creator with a gaming side, this is non-negotiable.

Motherboard, RAM & Storage

Motherboard: ASUS TRX50-SAGE WIFI ($500–700) is the professional Threadripper platform. It supports dual GPUs with proper PCIe bifurcation, excellent power delivery, and features for serious workstations. This is the foundation of a professional streaming studio.

RAM: 192GB DDR5 6400MHz is extreme but justified. Streaming at 4K, gaming, rendering, and multitasking simultaneously consume massive amounts of memory. 192GB ensures zero throttling even under the most demanding workloads. Professional streamers, video editors, and 3D artists benefit enormously.

Storage: 24TB NVMe PCIe 5.0 in RAID configuration. Stream archives, game libraries, project files, backups—everything fits. 8x3TB or 6x4TB Samsung 990 Pro drives in RAID 5 ($1,500–2,000) provide performance, capacity, and redundancy. Your stream archives are automatically backed up.

Case, PSU & Cooling

Case: Corsair 5000T RGB XL or Lian Li O11 Dynamic XL ($350–500) accommodate dual GPUs and dual cooling loops. You need serious space and thermals for this configuration. Both offer excellent build quality and showcase aesthetics.

PSU: 2500W 80+ Titanium (Corsair HX2500i, $600–800) is mandatory. Dual RTX 4090 under sustained load draws 800–900W. Threadripper 9980X peaks at 400–500W under heavy rendering. Streaming/encoding overhead adds another 50–100W. 2500W provides comfortable headroom and Titanium efficiency means minimal waste. Modularity is essential for cable management with this many components.

CPU Cooler: Dual custom loops with dedicated GPU water blocks ($1,000–1,500). One loop handles CPU and system; another loop cools both GPUs. This configuration requires planning but provides superior thermals and aesthetic appeal. Professional streaming setups demand professional cooling.

Total Build Cost Breakdown

GPU (Dual RTX 4090): $3,000–3,600 (75% of budget)

CPU (Threadripper 9980X): $800–1,000 (20% of budget)

Motherboard: $500–700 (12% of budget)

RAM (192GB DDR5): $600–900 (15% of budget)

SSD (24TB RAID): $1,500–2,000 (37% of budget)

Case: $350–500 (8% of budget)

PSU (2500W Titanium): $600–800 (15% of budget)

CPU Cooler (Dual Loops): $1,000–1,500 (25% of budget)

Total: ~$4,000 (±$300). This is professional-grade hardware where every component is top-tier and optimized for extreme workloads.

Performance Expectations

Local Gaming (Gaming GPU): 100–120 FPS (4K maximum)

Simultaneous Streaming: 4K 60 FPS to Twitch/YouTube

Baldur’s Gate 3: 110–130 FPS locally + 4K 60 FPS streaming

Cyberpunk 2077: 100–120 FPS locally + 4K 60 FPS streaming

Encoding Efficiency: H.265 encoding at professional quality

Local gaming and remote streaming both run at premium quality simultaneously. Viewers see beautiful 4K streams; you see buttery-smooth local gameplay. This is professional streaming reality.

Upgrade Path

Year 1–5+: This is the ultimate platform. Nothing needs upgrading for years. Dual RTX 4090, Threadripper 32-core, and 24TB storage handle everything.

Year 5+: If next-generation gaming or 8K streaming calls, upgrade GPUs. Everything else remains flagship.

Vs Other Tiers

$3,000 Build: Premium 4K — Excellent creative power, but single GPU limits streaming potential.

$2,500 Build: Smooth 4K — Good for gaming + light streaming, not professional streaming.

$5,000 Build: No Compromise — Adds even more storage and extreme overclocking support.

The $4,000 build is exclusively for professional streamers. The $3,000 build does excellent gaming and content creation; jump here if you need to stream 4K simultaneously with gaming. The jump to $5,000 adds marginal streaming improvements and extreme hardware redundancy.

For builders who want to push closer to the next tier, consider this complementary part for an upgrade path:

FAQ

Can one RTX 4090 do both gaming and streaming?

Technically yes, but performance suffers. One GPU can game at 80–90 FPS while streaming 1440p. This build’s dual-GPU approach removes that compromise—both local gaming and remote streaming run at maximum quality.

Is 192GB RAM necessary?

For professional streaming + content creation, yes. Streaming software, OBS, video editing applications, browser (for chat monitoring), and Discord all consume memory. 192GB ensures zero bottlenecks when multitasking at this scale.

Is 24TB SSD necessary?

For full-time streamers archiving streams, yes. Each hour of 4K 60 FPS streaming is ~100GB. 24TB fits 200+ hours of stream archives. Gaming libraries on top demand massive storage.

Final Verdict

The $4,000 build is the professional streaming platform. Dual RTX 4090, Threadripper 32-core, 192GB DDR5, and 24TB storage create a machine that streams 4K while gaming at 100+ FPS—true professional-grade streaming. If you’re a Twitch partner, YouTube streamer, or serious content creator, this is your machine. For pure gamers or casual streamers, the $2,000–$3,000 builds are better value.
