There are three important parts to finding a good gaming system:
1) The Graphics Card
2) The Processor
3) Knowing which Games.
You start with an understanding of current hardware. Know which is newest and what is out of date. The way I look at it is there are four tiers for processors and graphic cards:
1) Basic - This is the very minimum for basic operations and not to be considered for gaming.
------- For CPUS, this would be your Intel Celerons and Pentium processors.
------- For Graphic Cards, this would be your on-board graphics or cards with a "1" or "2" as the second digit of the model number (NVidia GT710)
2) Entry Level - This would be the bare minimum for most games. It might be below the minimum system requirements for some AAA games.
------- For CPUS, this would be your Intel Core I3 and AMD Ryzen 3 processors
------- For Graphic Cards, this would be your graphic cards with a 3, 4, or 5 as the second digit of the model number (AMD R5-240, NVidia GT1050)
3) Mainstream - This is pretty much the middle ground for games. This is the "I don't want to spend a fortune, but I want a decent gaming experience" level.
------- For CPUS, these would be your Intel Core I5 series and AMD Ryzen 5 series processors.
------- For Graphic Cards, these would be your graphic cards with a 5 or a 6 as the second digit of the model number (NVidia GTX1050Ti, AMD RX560)
4) Enthusiast - This is the "Money is no object" level. "I'm willing to spend a lot of money for my gaming experience".
------- For CPUS, these would be your Intel Core I7 series and AMD Ryzen 7 series processors.
------- For Graphic Cards, These would be your top end cards with a 7, 8, or 9 as the second digit of the model number (NVidia GT1080, AMD RX580)
Now as newer hardware is released, anywhere above where numbers are listed, can be fudged a bit and not everyone will agree with how I've laid things out (such and such card was AWESOME! There's no way it should be listed as a so-and-so card).
And, of course, you have your supporting components as well.
------- A good gaming system needs to have sufficient RAM to run the game, the OS, and any other background processes without running low.
------- A good gaming system needs a quality power supply in order to deliver the necessary power requirements without issues.
That's pretty much the basics of what I look for in a "gaming" system. Just because it says "Gaming System" in the product title doesn't mean it's a GOOD gaming system.
