You should have some idea at this point if you still want to get a graphics card or not. But to pick one that you want to buy, you’ll need to set a goal for yourself and carefully consider the limitations of your PC. Let’s start with the latter: those limitations. Every PC has a limited amount of room inside its case and a limited amount of power that its power supply can handle. If you don’t check the space available in your PC case before buying a card, you run the risk that it won’t fit, and you’ll be stuck buying a new case or having to return your card for another (smaller) one. If you don’t check how much power your PC's power supply can support before buying a GPU, things can go even worse. If you buy a card that needs more power than your PSU can handle, you could potentially damage your power supply or other parts by repeatedly pushing the power supply past its safe limit. Your system may also seem to work fine at times, but may crash periodically whenever the power draw rises too high. These problems are an inconvenience at the least, and they can be seriously troublesome issues at the worst. Both are easy to avoid if you simply check what your PC can support first before buying. If you are building a new PC from scratch, you’ll also want to make sure you buy a power supply and case accordingly that can handle all of your parts. Nvidia and AMD both outline recommended power supply wattage for each of their graphics card families. These estimates are typically quite conservative and above what is actually needed, but you should follow them nonetheless to avoid any issues. Your system needs to have a PSU that's up to the task of giving a new card enough juice. This is something to be especially wary of if you're putting a high-end video card in a pre-built PC that was equipped with a low-end card, or no card at all. Doubly so if it's a budget-minded or business system; these PCs tend to have underpowered or minimally provisioned PSUs. The two most important factors to be aware of here are the number of six-pin and eight-pin cables on your PSU, and the maximum wattage the PSU is rated for. Most cards beyond the most basic will require a six-pin cable, an eight-pin cable, or some combination of the two to provide working power to the card. (The very lowest-end cards draw all the power they need from the PCI Express slot they plug into.) Make sure you know what your card needs in terms of connectors. We've seen some changes here of late, as some of the GeForce RTX cards require a special adapter (it comes in the box) to turn two eight-pin PSU connectors into a single 12-pin one on the card. Also, a few other high-end monster cards now require a whopping three eight-pin connectors to suck down the required juice. Check that power supply (and the recommendation details for the specific card you are looking at) before dropping coin! Last, if you are upgrading an existing computer, it’s also important to know that a graphics card can end up bottlenecked and perform slower than expected if the rest of the system it is installed into isn’t fast enough to keep up. This mostly applies to the CPU that you pair the graphics card with, and to a far lesser extent the system’s RAM. We can’t give you ironclad, simple recommendations here, as faster GPUs will need faster CPUs, and slower graphics cards will work fine with slower processors. (Look to individual card reviews for more detail on that aspect.) We will give more direct advice here on our individual card recommendations, though.
