But if you’re upgrading a inexpensive or compact desktop (or any non-gaming PC, really), you need to check your power supply.
This standardized slot gives high-speed access to your PC’s processor and RAM, and its position on the board allows easy access to the rear of the case, letting you plug one or more monitors directly into the card itself.RELATED: Almost all modern graphics cards require a PCI-E x16 slot, and almost all motherboards that feature any full-sized PCI-E slots at all will have one.After narrowing that down, you’ll find that there are lots of card manufacturers making different cards based on either of those chipsets.In the end, there are hundreds of customized models available on the market.In other words, you can run an NVIDIA card just fine on a PC with an AMD CPU.
Before you go shopping for a new graphics card, you need to limit the parameters of your search to the cards that your system can actually run. If your computer has a free PCI-Express (PCI-E) slot and a decent power supply, it can probably run the lion’s share of modern graphics cards. Today’s graphics cards all use the PCI-E standard for plugging into your computer’s motherboard.The other thing to keep in mind is that a lot of the higher powered graphics cards are wide enough that they take up the space of two slots.If you’ve already got another type of card plugged in next to the slot you’ll use for your graphics card, you’ll need to take that space limitation into account.Make sure your power supply has at least that much available (with a 30-40w safety margin) before making your final choice.If it doesn’t, you need to choose a less powerful card or upgrade your power supply at the same time.Also some very small PC cases might limit the height of the card you can use.
