From Xfire: "Gaming desktops are more powerful than they've ever been. Unfortunately, not everyone can afford to get themselves the latest and most powerful graphics card right now. Not especially given the current situation, with cryptocurrency miners driving up the prices of even entry-level gaming graphics cards like the GTX 1050 ti.
With that said, not every game out there demands a powerful PC. In fact, in this day and age, some of the best games on PC can be played even if your desktop doesn't have a graphics card."
