Graphics cards are the main event when it comes to PC hardware, and gaming. Graphics cards are considered to be the most popular thing in the PC because it is what renders graphics. One graphics card is enough, seeing as it is dedicated to making the graphics, that the HDMI, VGA, or DVI cable translates into a visible image. Some graphics card can crush benchmarking programs and video games that require the most expensive and high tier parts, but even the best cards have their downsides.

A NVIDIA Titan X graphics card is still the reigning champion in this graphics card battle, coming in with a $1,100 price tag. Such power, you would think it would be able to handle everything and should be able to play anything, but this is the complete opposite. When it comes to the latest titles most PC’s even with this power cannot run games to their full potential in 4k resolution. 1080p however is really easy on these expensive cards, and allows for a solid frame rate across the board with little to no frame loss. 4k is still something that the PC community still has to work on because; no graphics card is able to run a 1080p game like a 4k game yet. This is why there are technologies for the latest graphics card; they are called NVIDIA SLI and AMD Crossfire. This allows for two to four graphics card to be installed into a system and allows for both of their powers to be combined. This is not very beneficial to someone who plays on a single monitor in 1080p, or a single 4k monitor. This is for the people who have the most demanding setups out there. Like for instance someone who has four, 4k monitors may want to invest the extra money into getting 2-4 of the same graphics card so that their clock speeds are combined and that the monitors each have their own graphical processors.

The SLI stands for scalable link interface which is just a term that means it allows for graphics card to combine their speeds and scale up frame rates on the same interface (computer.)  As an enthusiast of this type of tech I cannot recommend do this to your pc unless you have some money to burn on your PC and just want a few extra frames just like everyone else.
