With exciting new PC game titles coming out constantly, you might find your trusty old PC coming up short in the Frames Per Second department. If you're experiencing screenlag, stuttering or having to resort to low/medium graphics settings to keep a game playable, these are clear indications that it's time for an upgrade. You don't have to buy a complete new system to be able to enjoy your brand new games.

Believe it or not, just upgrading your graphics card will make a world of difference!

We understand that not all gamers follow the latest hardware developments or are aware of the fact that you can quite easily upgrade most of your PC components yourself. All you need to know is how to do it, which is why we're here to offer a hand for fellow gamers-in-need. We'll walk you through the basics of a PC so you know what you're dealing with and how to safely upgrade your graphics card.

Step 1: The Basics of a PC

  • Computer Case
    The case of your PC houses all the hardware components that do the work, this is where the magic happens. Computer cases come in many shapes and sizes, but usually they will look like a tower made from steel or aluminum. To access the components inside of a case, you can safely remove one or both of the side panels and have a look inside. It's recommended to make sure your PC is turned off and disconnect all cables that are connected to the case before you open it. Go ahead, take a look!
  • Components inside
    The components you find inside your case will vary per PC, but it will always contain these basic ingredients that are essential for a computer.

    1. Motherboard
    2. Central Processing Unit (CPU)
    3. Random Access Memory (RAM) modules
    4. Power Supply Unit (PSU)
    5. Storage in the form of either Hard Disk Drives (HDD) or Solid State Drives (SSD)
    6. Graphics Card containing the Graphics Processing Unit (GPU)*
      *This is optional, as some systems might have an integrated graphics chipset, which means it is integrated on the motherboard or in the CPU.
    7. Cables, LOTS of cables.


  • PCI-e slots on Motherboard
    We won't go into unnecessary detail here, but what you need to understand is that every single component is connected to the motherboard in one way or another. Dedicated Graphics Cards for consumers are almost always connected to the motherboard by a PCI-Express (PCI-e) slot. There are multiple variations of PCI-e slots, the most common are x16, or x4. Always remember that a Graphics Card needs to be placed into a x16 slot, which is physically the longest PCI-e slot.


Step 2: Getting ready

  • Buy a new graphics card
    This might be an obvious one, but make sure you buy a graphics card that will be able to run the games you want to play. There are plenty of tech websites that provide performance test results of graphics cards like Tom's Hardware. Our current lineup of Twin Frozr VI series graphics cards are powerful enough for playing the latest games.
  • Toolbox
    Even though a PC is a digital computer, replacing any component will still require you to 'go under the hood' and physically replace something. For upgrading your graphics card, we recommend that you have a set of Phillips screwdrivers close.
  • Uninstalling old VGA drivers
    Before you go ahead and start physically replacing the graphics card, it's important to uninstall your old graphics card drivers. Check to see if your old graphics card is an AMD/ATI or NVIDIA based one, then uninstall the old drivers as described on the links below:
    - Uninstalling AMD graphics drivers
    - Uninstalling NVIDIA graphics drivers
  • Power off your PC, unplug all the cables
    Once you have successfully uninstalled your old drivers and shut down your PC, make sure you unplug all the cables that are plugged into the case. Most power supply units have a manual I/O switch on the back of the case, make sure this is set to O. Then proceed to unplug the power cable from the back of the power supply unit.
  • Dusting - While you're in there
    After using a PC for months or even years, it can get quite dusty on the inside. The dust can affect your PC's performance and cause all kinds of problems, so it's best to carefully clean it by using a vacuum cleaner to suck up most of the dust. Be careful not to hit any components while you do this!


Step 3: Replacing your graphics card

  • Unscrew slots
    Typically, a graphics card is not just plugged into a PCI-e slot on the motherboard, but it is also secured with a screw at the backside of the case. With the side cover of the case removed, you should be able to see and access the screw(s) clearly. Depending on how big the graphics card is, it will be secured with either one or two screws. To be able to remove the graphics card, remove the screw(s) holding it in place.
  • Unplug power connectors
    The more powerful a graphics card is, the more power it will need to work. This means that many graphics cards today have separate 6- or 8-pins power connectors located at the top end of the card. If your old card has one or more of these cables plugged into it, go ahead and carefully unplug them before moving on.
  • Plug out, Plug in
    Once the old card is unplugged and no longer secured to the case with screws, you can gently push down or pull on the catch at the end of the PCI-e slot that holds the graphics card in. You should now be able to lift the old graphics card out of the case and replace it with the new graphics card. Once the new graphics card is placed in the PCI-e slot, make sure you secure it to the case by using the screws you removed from your old graphics card. Also don't forget to connect the power connectors at the top end of your new graphics card, this should be either 6- or 8-pins connectors coming from the power supply.

Step 4: Finishing up

  • Putting humpty dumpty back together again
    After replacing your graphics card, the time has come to put your PC back together again. For the first time you start however, you might want to keep the side panel off. This will enable you to see if the fans on your new graphics card spin up when you start the PC.
  • Reconnect all the cables
    Plug all the cables that you've unplugged in step 2 back in again and put the power switch on your power supply back on I. Make sure you have all your peripherals correctly plugged in or your system might not work correctly. This means your power cable, monitor(s), mouse, keyboard and Ethernet (LAN) or any other devices you have.
  • Start your PC
    When you're sure that everything is plugged in correctly, press the power button and watch closely what happens. If your monitor shows the information it normally does when you start your PC, that's a good sign! Let it start up into Windows before the next step.
    If your PC does not start or your monitor does not display anything after the PC starts up, check again if all the cables are plugged in correctly (don't forget the 6- or 8-pin power connectors on your graphics card!) and your monitor is turned on. If this doesn' t solve it, turn off the PC by pressing and holding the power button. Then turn it back on and watch closely if the fans of your graphics card start spinning in the first seconds after turning the PC on. If the fans do not start spinning, this might indicate a problem with the graphics card, in which case you should contact customer support.
  • Download & Install latest drivers
    If everything goes according to plan, your PC should start up and you will be looking at your desktop. Before you start up your favorite game to see how well your new graphics card performs, you should first download the latest graphics card drivers from either AMD or NVIDIA depending on your graphics card. After you select and install the latest drivers for your graphics card, you should be good to go!

Step 5: Time for GAMING!

  • Play your favorite games
    We don't have to explain this, do we? Start up your favorite game and see how it plays now. If you've done it right, you should notice a significant increase in performance by more frames per second. Meaning it will look and feel much smoother while playing. This would also be the ideal time to increase the graphics settings in the game and see how awesome the game looks in high, very high or ultra graphics settings!
