Keeping this in consideration, can you use 2 graphics cards at the same time?

If you have 2 identical video cards, enough PCI slots on your motherboard, and enough spare output from your power supply, then yes. You can bridge two video cards together. Nvidia calls their implementation of this SLI, while the AMD version is called Crossfire.

Beside above, does having 2 GPUs increase performance? The primary benefit of running two graphics cards is increased video game performance. When two or more cards render the same 3D images, PC games run at higher frame rates and at higher resolutions with additional filters. This extra capacity improves the quality of the graphics in games.

One may also ask, can you put 2 GPU on any motherboard?

The answer is YES, but you need to make sure that your motherboard supports multi-gpu or SLI/CrossFireX. Every mainstream cpu like i5 8600k or i7 8700k supports 16 pci-e lanes. That means, that they are prepared to utilize one GPU as common, or SLI/CF configuration with dual-GPU setup at 8-8 configuration.

Is it worth having 2 graphics cards?

Using two (or more) video cards in tandem—known as "SLI" for NVIDIA cards and "Crossfire" for AMD cards—can get you better performance, sometimes even for less money than you'd spend on a comparable single card solution. However, whether it's worth it is another story. Here's what you need to know.
