You won't regret it, I don't think. Sans the dreadfully bad pitching game (I just flat out don't play pitch shots in this game), the rest of the short game in 2K21 pretty good. I find the chipping better this year, although I still think they could make it more proportional in feel.
If your PC can run this game at 60 FPS in 4K, you're in for a real treat. I've never played a game in my life that got more of a boost, going from 30 to 60 FPS than this one. I cannot make myself play the XBox One X version again now, having tasted it on my PC... I just wish I could have got my copy at $30, versus the $60 I paid for it, but I can't say I haven't gotten my money's worth out of it.
