Is there an external graphics card for use on a 2018 intel Mac Mini?

[DavidInSydney]

Our 2018 MAC MINI SG/3.0GHZ 6C/8GB/512GB can be very slow when using the Cintiq 22 inch with Photoshop and animation programs such as ToonBoom Animate etc. A friend suggests we buy an exterior graphics card, plugging it in to one of its Thunderbolt 3 (USB-C) ports.

Is this a good idea and can anyone suggest a suitable graphics card?
