      <h2>The Core Conflict</h2>
      <p>At the heart of every gaming PC is a constant, high-speed conversation between your CPU and your GPU. The CPU is the "brain" that processes game logic, physics, and sends rendering commands. The GPU is the "artist" that takes those commands and draws the beautiful images you see on screen. A bottleneck occurs when one of these components works significantly faster than the other, leaving one waiting and wasting its potential.</p>
      <h2>What is a GPU Bottleneck?</h2>
      <p>This is the most common scenario for gamers, especially at higher resolutions like 1440p and 4K. A GPU bottleneck means your CPU is ready to push out more frames, but the GPU can't keep up with the demand of rendering them. You'll often see your GPU usage at 99-100% while your CPU usage is much lower. While it sounds bad, this is often the *ideal* scenario, as it means you're getting the absolute maximum performance from your most expensive gaming component.</p>
      <h2>What is a CPU Bottleneck?</h2>
      <p>A CPU bottleneck happens when the roles are reversed. Your GPU is powerful and has rendering headroom to spare, but it's sitting idle, waiting for the CPU to send it the next set of instructions. This is common in fast-paced competitive games running at lower resolutions (like 1080p), where frame rates can be extremely high. In this case, upgrading your CPU would lead to a significant performance uplift.</p>
    

PC Bottlenecks Explained: CPU vs. GPU


      <h2>Beyond Capacity</h2>
      <p>For years, the main advice about RAM has been "get 16GB for gaming." While capacity is crucial, it's not the whole story. The speed of your RAM, measured in megahertz (MHz), and its timings (or latency) play a vital role in how quickly your CPU can access data. For certain CPUs, especially AMD's Ryzen series, this speed can directly impact gaming performance.</p>
      <h2>The Sweet Spot</h2>
      <p>So, do you need the fastest RAM on the market? Not necessarily. There's a point of diminishing returns. For most modern systems (both Intel and AMD), a 32GB kit of DDR5 RAM running at 6000MHz with low CL (Cas Latency) timings is considered the "sweet spot." It provides a noticeable performance boost over baseline speeds without the exorbitant cost of enthusiast-grade, high-frequency kits.</p>
      <h2>When Does It Matter Most?</h2>
      <ul>
        <li>
          <strong>CPU-Bound Scenarios:</strong> Faster RAM helps the CPU process and feed data to the GPU more quickly, which is most beneficial when you're CPU-bottlenecked (e.g., playing at 1080p with a high refresh rate).
        </li>
        <li>
          <strong>Integrated Graphics:</strong> If you're gaming on an APU without a dedicated graphics card, faster RAM is critical, as the integrated GPU uses your system RAM as its video memory (VRAM).
        </li>
      </ul>
      <p>While a GPU upgrade will almost always give you a bigger FPS boost, choosing the right RAM is an important part of building a well-rounded, snappy system.</p>
