"Doubts about graphics compatibility
Hello everyone, I am thinking about buying an Intel graphics card and I want to know if any of you have or have tried these games on Intel graphics and what has been your experience"

That's a strange question. There's only really two types for use with a Windows PC. Nvidia and AMD. Nvidia have been in common use for decades, and AMD is starting to become more popular. It's doubtful you would notice which type is fitted once fitted! The main thing is what power of GPU to buy, and what size RAM. The best are very expensive.
