What Graphics Cards Are Compatible With My PC

Upgrading an aging PC with new hardware may appear to be a nightmare. Wasn’t it once said that placing new wine in old bottles is a sensible thing to do? However, you might be amazed at how far back you can go with desktop PCs and still install a cutting-edge graphics card. GPUs like the Nvidia RTX 2080 Ti and AMD Radeon RX 5700 XT, for example, maybe used in almost every PC manufactured in the last decade—and perhaps even before. However, there are certain limitations, especially if your machine is growing old.

Do you have a PCIe x16 slot?

PCI Express’s incredible backward compatibility guarantees that even the most recent, high-end graphics cards can be plugged into a motherboard from the George W. Bush era. In principle, any card that can fit in a slot will function, from t he initial PCIe 1.0a/1.1 up to the most recent PCIe 4.0, and even future PCIe 5.0 and 6.0 standards. PCIe x1 cards can be installed in x16 slots, as can x16 slots with just x4 link widths, and anything in between. (There may be outliers, but they are usually due to poor PCIe implementation or faulty firmware.) When you think about it, that’s really amazing, especially in light of prior standards that were set.

How Much Room Do You Have in Your Case?

That isn’t to say that any old PC with a PCIe x16 slot can’t support the newest graphics cards; however, this is generally due to other hardware requirements. Size is an example: You’re not going to be able to put a 320mm graphics card into a case designed for a 270mm card. Many small PCs will be limited in terms of what they can fit, and pre-built systems frequently fall into this category.

You may check your case manual, if you have one, to find out how large your GPU can be. You’re unlikely to locate it or be able to find it online for pre-built PCs. Best Gaming Tips recommend going old-school and measuring using a ruler or measuring tape; it will likely take less time and provide more accurate results.

Do You Have the Correct Power Supply?

Another big stumbling block is the necessity for power. If your PC was manufactured before 2015, there’s a high possibility your power supply lacks the 8-pin PCI Express Graphics (PEG) power connections used on many of today’s faster cards. 6-pin PEG connections have been around for a long time, however, some low-cost power supplies still don’t include them. If you have a PC from a big OEM (for example, Dell, HP, or Lenovo), you may not be able to replace the power supply with a later model that has the requisite 6- or 8-pin connections.

Are your other components adequate?

Of course, just because you can do something does not mean you should. I still have an old Intel Core i7-965 PC lying around that was a beast when I built it in early 2009. It can still accomplish the majority of what you may want to do on a PC more than a decade later, and it has been updated several times over the years. It can even use a GeForce RTX 2080 Ti GPU and run any game on the market. It will not, however, run every game at high framerates.


My computer has an Intel Pentium D processor and the only type of graphics card which is compatible with this is an Intel 82845G Express Chipset Family. I am not looking to play newer games on it but would like to use Adobe Flash Player 10 or higher (Adobe recommends “512 MB VRAM” for Aero rendering). I am currently using an NVIDIA GeForce 710 video card which came installed when I purchased this PC several years ago (I think this one has 32MB VRAM). Will that work OK?
