PC building costs range from $400 to $3,000 or more, depending on what you want the computer to do

The total cost depends on four things: the processor, graphics card, storage, and how much power you need. A basic machine for web browsing and office work runs $400 to $600. A gaming PC that plays modern games at high settings costs $1,200 to $2,000. A workstation for video editing or 3D rendering can exceed $3,000. You also need to buy an operating system (Windows costs $100 to $140), a monitor, keyboard, and mouse—those add another $200 to $500 if you don't already own them.

The single most expensive part is usually the graphics card, which can range from $150 for basic gaming to $800 or more for high-end gaming or professional work. The processor (CPU) is typically the second-largest expense. Everything else—motherboard, RAM, power supply, case, cooling—costs less individually but adds up quickly.

Key Takeaways

  • A budget gaming or work PC costs $800 to $1,200 before monitor and peripherals; a high-end gaming or professional machine costs $1,800 to $3,000 or more.
  • The graphics card and processor account for 40 to 60 percent of your total cost, so choosing these first determines your overall budget.
  • You will need to buy Windows ($100 to $140), a monitor ($150 to $400), and a keyboard and mouse ($50 to $150) separately unless you already own them.
  • Prices for graphics cards and processors fluctuate month to month, so the same build may cost $100 to $300 more or less depending on when you buy.
  • Building the PC yourself saves $100 to $300 compared to buying a pre-built machine with the same parts, but requires a few hours and basic tools.

Budget PC: $400 to $700

A budget build handles everyday tasks—email, web browsing, video streaming, light photo editing, and older games. The processor is typically a mid-range chip like an AMD Ryzen 5 5500 or Intel Core i5-12400, which costs $100 to $150. You pair it with 16 gigabytes of RAM ($40 to $60) and a 500-gigabyte solid-state drive ($40 to $60). Storage is tight, but you can add a second drive later.

The graphics card in a budget build is often integrated into the processor itself, meaning you don't buy a separate card. If you do want a dedicated graphics card for light gaming, add $150 to $250 for something like an NVIDIA GTX 1650 or AMD RX 6500 XT. The motherboard, power supply, and case together run $150 to $250. Total: $500 to $700 for the computer itself, plus $100 to $140 for Windows.

Mid-Range Gaming PC: $1,000 to $1,500

A mid-range gaming build plays modern games at 1080p resolution (standard monitor size) at 60 to 100 frames per second on high settings. The processor is a Ryzen 5 7600X or Intel Core i7-13700K, costing $200 to $350. RAM is 32 gigabytes ($60 to $100), and storage is a 1-terabyte SSD ($60 to $100).

The graphics card is the biggest expense here: an NVIDIA RTX 4060 Ti or RTX 4070, which costs $400 to $600. The motherboard, power supply (650 to 750 watts), and case run $200 to $300 total. Add a CPU cooler if the processor doesn't come with one ($30 to $80). Total: $1,100 to $1,500 for the computer, plus Windows and peripherals.

High-End Gaming or Professional PC: $1,800 to $3,500

High-end builds are for gaming at 1440p or 4K resolution, or for professional work like video editing, 3D rendering, or software development. The processor is a top-tier chip like a Ryzen 9 7950X or Intel Core i9-13900K, costing $400 to $700. RAM jumps to 64 gigabytes ($120 to $200), and storage is 2 to 4 terabytes of SSD ($150 to $300).

The graphics card is the major cost: an NVIDIA RTX 4080 or RTX 4090, which runs $1,000 to $1,600. The motherboard, power supply (850 to 1000 watts), and case cost $250 to $400. A high-end CPU cooler runs $80 to $150. Total: $2,000 to $3,500 for the computer, plus Windows and peripherals.

Parts You Need to Buy Separately

Windows 11 Home costs $100 to $140 and is required to run the computer (unless you use a free operating system like Linux). A monitor runs $150 to $400 depending on size and refresh rate; a 1080p 24-inch monitor is $150 to $200, while a 1440p or high-refresh gaming monitor is $250 to $400. A keyboard and mouse together cost $50 to $150 for basic models, or $150 to $300 for gaming-grade peripherals.

If you don't already own these items, add $300 to $650 to your total build cost. If you already have a monitor, keyboard, and mouse, you only need to buy Windows.

Why Prices Change Month to Month

Graphics card and processor prices fluctuate based on supply, demand, and new product releases. A graphics card that costs $500 one month might cost $450 the next, or $550 if a new model launches and older stock sells out. Processor prices typically drop when a newer generation is released, sometimes by $50 to $150.

RAM and SSD prices also shift, though usually by smaller amounts ($10 to $30). If you see a part you want at a good price, buying it when ready is often smarter than waiting, because prices are unpredictable. Checking price-tracking sites like PCPartPicker or CheapShark shows you historical pricing and alerts you when a part drops in price.

Building vs. Buying Pre-Built

A pre-built PC with the same parts costs $100 to $300 more than building it yourself, because the manufacturer charges for assembly and labor. Building takes 2 to 4 hours the first time, and you need a Phillips screwdriver, a grounding strap (optional but recommended, $5 to $15), and a flat surface to work on. The process is straightforward: install the power supply, motherboard, CPU, RAM, storage, and graphics card into the case, then plug in cables.

You save money by building, but you also take on the responsibility of troubleshooting if something doesn't work. Most parts come with a warranty, so if a component fails, you can return it. Many people find the learning experience worth the time investment, especially if they plan to upgrade or repair the PC later.

Frequently Asked Questions

Can I build a PC for under $500?

Yes, but it will be basic. A $400 to $500 build handles web browsing, email, and video streaming, but struggles with gaming or heavy software. You'll need to use the graphics built into the processor rather than buying a separate graphics card. Storage and RAM will be minimal, so you may run out of space quickly.

How much should I spend on a graphics card?

Spend 25 to 40 percent of your total budget on the graphics card. For a $1,200 build, that's $300 to $480. For a $2,000 build, that's $500 to $800. The graphics card has the biggest impact on gaming performance, so it's worth prioritizing, but don't overspend on a card that's more powerful than your processor can handle.

Do I need to buy Windows, or can I use it free?

Windows 11 costs $100 to $140, but you can install it free and use it with a watermark on your desktop. You can set up it later when you have the money. Linux is a free alternative operating system, though fewer games and professional programs run on it. macOS is not an option for a custom-built PC.

What's the difference between a gaming PC and a work PC?

A gaming PC prioritizes a powerful graphics card and fast processor for frame rate and speed. A work PC (for video editing, 3D rendering, or coding) prioritizes RAM and processor cores for handling large files and complex calculations. A gaming PC with an RTX 4070 costs more than a work PC with the same processor, because the graphics card is expensive.

Will my build be outdated in a year?

No. A PC built today will play current games and run current software for 3 to 5 years without major upgrades. Graphics cards and processors improve every 1 to 2 years, but older hardware remains functional. You can upgrade individual parts—like adding more RAM or a larger SSD—without replacing the whole computer.
