Don't forget the PSU and that you can't overclock the K processors on B250 mobos. Gonna need a Z270 board.
It should run most of those games you mentioned but I haven't played Forza Horizon. Get a SSD if you have the money.
I know this was over a week ago, but I think there was some advice you weren’t explicitly saying that TinyBuilder might have missed. Tiny: do not buy a K chip if you aren’t planning to overclock it. There’s no point. Save the money and buy another chip (which will probably come with a stock fan that’d work fine for you).
Hey Triniking, I finished my build a while ago and thought I would get back to you. Thank you so much for your help. The games run fine and without a hitch thank you again!
