What is a good PC to get that isn’t overly expensive?

Hi! So I’m currently wanting to buy a gaming PC. I have next to no experience when it comes to PC’s. I’ve been a console guy my whole life. The reason I want one is to get the game Prehistoric Kingdom. I’m actually studying to be a paleontologist and PK looks to be the best piece of Paleomedia I’ve ever seen and I absolutely have to get it. There in lies my problem cause I don’t want to spend a boat load of money on a PC that I’d be getting for just one game. Does anyone have any suggestions for a PC that’s not overly expensive and runs Prehistoric Kingdom smoothly and well?
