How To Build A Low Budget Pc That Can Still Run Modern Games

Building a gaming PC doesn’t have to cost over $1,500. With careful planning, strategic part selection, and an understanding of where performance matters most, it’s entirely possible to assemble a capable machine for under $700 that runs modern titles at playable frame rates. The key lies in balancing value, compatibility, and future-proofing without overspending on unnecessary specs.

Modern games demand more from hardware than ever—higher resolutions, real-time ray tracing, and complex physics engines push even mid-range systems to their limits. However, many AAA titles offer scalable settings, allowing lower-end hardware to deliver smooth 60+ FPS experiences at 1080p with medium or high settings. This guide walks through the essentials of building a budget-friendly gaming rig that punches above its price tag.

1. Define Your Budget and Performance Goals

Before purchasing any components, establish a clear budget and realistic expectations. A $600–$700 range is ideal for a functional modern gaming PC. Within this bracket, you can expect:

• Smooth gameplay at 1080p resolution
• 60+ FPS in most esports titles (e.g., Valorant, CS2, Apex Legends)
• 40–60 FPS in demanding AAA games with optimized settings
• Upgrade paths for future GPU or RAM improvements

It’s important to accept trade-offs: no 4K gaming, limited ray tracing support, and modest multitasking ability. But for dedicated gamers who prioritize playing rather than streaming or content creation, this setup delivers excellent value.

Tip: Always allocate slightly more to the GPU than the CPU—it has a greater impact on gaming performance.

2. Choose Components Wisely: The Core Building Blocks

Selecting the right parts within a tight budget requires research and compromise. Below is a breakdown of each essential component and what to look for.

CPU: Balance Power and Compatibility

The CPU handles game logic, AI, and physics calculations. For budget builds, AMD Ryzen processors offer superior value due to integrated graphics and strong multi-core performance.

A Ryzen 5 5600G is a standout choice. It includes Vega 7 integrated graphics, useful if your GPU arrives late or fails. More importantly, it supports PCIe 4.0 and AM4 motherboards, which are widely available and affordable.

“Even entry-level CPUs today are powerful enough for gaming when paired with a decent GPU.” — Linus Sebastian, Tech Educator & Founder of Linus Tech Tips

Motherboard: Stick to B550 or A520 Chipsets

For the Ryzen 5 5600G, a B550 motherboard offers great value with PCIe 4.0 support and room for upgrades. If you're tightening the budget, an A520 board works but lacks some features like overclocking and multiple M.2 slots.

Ensure the board has at least two RAM slots, USB 3.0 ports, and built-in Wi-Fi if you plan to avoid Ethernet cables.

GPU: The Most Important Investment

This is where most of your budget should go. Integrated graphics won't handle modern games well beyond low settings. Aim for a discrete GPU such as:

• NVIDIA GeForce GTX 1660 Super / RTX 3050 (used market)
• AMD Radeon RX 6600 / RX 6650 XT

The RX 6600 consistently outperforms the GTX 1660 Super and rivals the RTX 3050 at a lower price. It delivers 60+ FPS in Cyberpunk 2077 at 1080p with FSR enabled and excels in titles like Elden Ring, Horizon Zero Dawn, and Hogwarts Legacy.

RAM: 16GB Dual Channel Is Essential

8GB is no longer sufficient for modern gaming. Many titles now require 12–16GB just to run smoothly. Opt for 16GB (2x8GB) DDR4 3200MHz CL16 memory in dual-channel configuration. This ensures optimal bandwidth for both the CPU and integrated graphics if needed temporarily.

Storage: NVMe SSD Over HDD

An SSD drastically improves load times and overall system responsiveness. A 500GB NVMe M.2 SSD costs under $40 and provides fast boot and game loading. Avoid traditional hard drives as primary storage—they bottleneck modern games.

PSU: Never Skimp Here

A reliable power supply protects your investment. Choose a 550W–650W 80+ Bronze certified unit from reputable brands like EVGA, Corsair, or Seasonic. Look for full modular or semi-modular designs for easier cable management.

Case: Function First

Pick a case with good airflow and space for cable routing. Models like the Fractal Design Focus G or NZXT H510 Core offer clean aesthetics and solid build quality under $70. Ensure it fits your motherboard size (ATX/micro-ATX) and has room for GPU clearance.

Tip: Watch for seasonal sales (Black Friday, Prime Day) to save 10–20% on select parts.

4. Step-by-Step Assembly Guide

Once parts arrive, follow these steps carefully to assemble your PC:

1. Prepare your workspace: Use a non-static surface, gather tools (Phillips screwdriver, zip ties), and ground yourself by touching metal.
2. Install CPU and cooler: Open the socket on the motherboard, align the CPU (match triangle markers), gently place it, and lock the lever. Apply thermal paste if not pre-applied, then attach the stock cooler.
3. Insert RAM: Push down the clips on the DIMM slots, align the notch on the RAM stick, and press firmly until it clicks into place. Use slots A2 and B2 for dual-channel mode.
4. Mount M.2 SSD: Insert the NVMe drive into the M.2 slot at a 30-degree angle, secure with a screw, then press down flat.
4. Install motherboard: Place standoffs in the case, position the board, and screw it in securely without over-tightening.
5. Install PSU: Slide it into the rear chamber, align screw holes, and fasten. Route the main 24-pin and CPU 8-pin cables through the back panel cutout to the motherboard.
6. Install GPU: Remove case and motherboard slot covers, insert the card into the top PCIe x16 slot, and secure with screws. Connect PCIe power cables from the PSU.
7. Connect front panel wires: Attach power switch, reset, HDD LED, and USB/audio headers using the motherboard manual as reference.
8. Power on and test: Connect monitor, keyboard, and power cord. Turn on the PSU switch and press the power button. If the system boots, enter BIOS to confirm RAM speed and boot device.
9. Install OS: Boot from a Windows USB installer, format the SSD, and complete installation. Update drivers via motherboard and GPU manufacturer websites.

Taking your time during assembly prevents damage and ensures stability. If the system doesn’t POST, double-check RAM seating, power connections, and GPU installation.

5. Real-World Performance Example

Consider Mark, a college student in Chicago who wanted to play Warzone and Starfield without breaking the bank. He followed a similar $650 build using a Ryzen 5 5600G and RX 6600. After installing Windows 11 and updating drivers, he tested several games:

• Call of Duty: Warzone – 85 FPS average at 1080p High settings
• Elden Ring – 60 FPS stable with shadows and textures on High
• Hogwarts Legacy – 50 FPS using FSR Balanced mode
• CS2 – 140+ FPS on max settings

Mark reported being “shocked” at how well the system performed. “I thought I’d need to spend $1,000,” he said. “But this runs everything I care about smoothly.” His only upgrade later was adding a second 500GB SSD for extra storage.

Optimization Tips for Maximum Performance

Even with limited hardware, software tweaks can boost performance:

• Enable FidelityFX Super Resolution (FSR) or NVIDIA DLSS in supported games to increase FPS.
• Cap frame rates at 60 or 75 FPS to reduce screen tearing and GPU load.
• Disable background apps in Windows Settings > Apps > Startup.
• Update GPU drivers monthly using AMD Adrenalin or NVIDIA GeForce Experience.
• Set Windows power plan to “High Performance” for consistent clock speeds.

Tip: Lower in-game settings like ambient occlusion, volumetric fog, and motion blur for noticeable FPS gains with minimal visual loss.

FAQ: Common Questions About Budget Gaming Builds

Can I use integrated graphics instead of a GPU?

Only for very light gaming. Modern integrated graphics like Vega 7 or Intel Iris Xe can run older or indie titles (e.g., Minecraft, Stardew Valley) at 1080p, but struggle with AAA games. Even entry-level GPUs like the RX 6400 outperform iGPUs significantly.

Is it cheaper to buy a prebuilt PC?

Sometimes, but prebuilts often include lower-tier components (e.g., OEM PSUs, slow SSDs). Building yourself ensures transparency, better part quality, and easier upgrades. You also learn valuable troubleshooting skills.

How long will this kind of PC last?

A well-chosen $600–$700 build should remain viable for 3–4 years. As games grow more demanding, you can upgrade the GPU later (e.g., to an RX 7700 XT or RTX 4060) while reusing the rest of the system.
