Processor (CPU): AMD Ryzen 7 7800X3D

Price: ₹40,000 (approx.)

The Ryzen 7 7800X3D is AMD’s gaming champion, featuring 8 cores, 16 threads, and a massive 96MB L3 cache thanks to 3D V-Cache. This reduces latency in CPU-bound games like Cyberpunk 2077 and Starfield, delivering up to 15% higher FPS over non-3D CPUs. Its 120W TDP ensures compatibility with mid-range cooling solutions, though liquid cooling is recommended for sustained boosts.

Why It Fits:

• Unlocks Smart Access Memory (SAM) when paired with an AMD GPU, boosting performance by 5-10%.
• PCIe 4.0 support ensures no bottlenecks for the RX 7900 XTX.

Graphics Card (GPU): AMD Radeon RX 7900 XTX

Price: ₹95,000 (approx.)

The RX 7900 XTX features 24GB GDDR6 memory, 6,144 stream processors, and a 384-bit bus. Built on RDNA 3 architecture, it supports hardware-accelerated ray tracing, FSR 3 Frame Generation, and AV1 encoding.

Key Specs:

• 4K Performance: 60–100+ FPS in AAA titles like Alan Wake 2 with FSR 3 enabled.
• FSR 3 Advantage: Boosts frame rates by up to 2x in supported games (e.g., Forspoken, Immortals of Aveum).
• Power Draw: 355W TGP (requires a robust PSU).

Why It Fits:

• SAM compatibility with Ryzen 7000 CPUs for optimized memory access.
• Better value than NVIDIA’s RTX 4080 in rasterized gaming.

Motherboard: MSI MAG B650 Tomahawk WiFi

Price: ₹22,000 (approx.)

A cost-effective AM5 motherboard with PCIe 5.0 support, DDR5 compatibility, and robust VRMs for the 7800X3D. Features:

• BIOS support for SAM and Precision Boost Overdrive (PBO).

Why It Fits:

• Balances price and features for AM5 builds.
• Enables SAM for free performance gains.

RAM: ADATA XPG Lancer Blade 32GB DDR5-6000 CL30

Price: ₹16,000 (approx.)

AMD’s Ryzen 7000 series thrives on DDR5-6000 with low latency. This 32GB kit (2x16GB) hits the sweet spot for gaming and multitasking.

Why It Fits:

• CL30 timings reduce latency for smoother frame pacing.
• EXPO profiles for one-click AMD optimization.

Storage: Kingston KC3000 2TB NVMe PCIe 4.0 SSD

Price: ₹15,000 (approx.)

With read/write speeds up to 7,000/6,000 MB/s, this SSD ensures rapid game load times and snappy system responsiveness.

Why It Fits:

• PCIe 4.0 maximizes bandwidth for DirectStorage-enabled games.
• 2TB capacity accommodates large game libraries.

Power Supply: Deepcool PQ1000M 1000W 80+ Gold

Price: ₹12,500 (approx.)

The RX 7900 XTX’s transient power spikes demand a reliable PSU. This 1000W unit offers:

• ATX 3.0 compliance for GPU power stability.
• Native 12VHPWR connector (adapter included for AMD GPUs).

Why It Fits:

• Headroom for overclocking both CPU and GPU.
• 80+ Gold efficiency reduces power waste.

Cooling: Deepcool AK620 Digital Air Cooler

Price: ₹6,500 (approx.)

A dual-tower air cooler with a digital display for real-time CPU temp monitoring. Handles the 7800X3D’s thermal load quietly.

Why It Fits:

• Cost-effective alternative to AIOs without sacrificing performance.
• Matches AMD’s 120W TDP requirements.

Case: Corsair 4000D Airflow

Price: ₹8,500 (approx.)

A mid-tower case with excellent airflow, supporting GPUs up to 360mm (the 7900 XTX is 287mm).

Why It Fits:

• Mesh front panel for optimal cooling.
• Easy cable management and tempered glass aesthetics.
