Ya Intel Does domin
ate pretty much everything.
But I'm addressing your price range though, If you have the money, I suggest going with what your dad says.
But keep in mind that you're going to either have to stick with Intel integrated graphics for a while, or spend more from the beginning and get a graphics card immediately.
When it comes to price/performance, AMD dominates market for less expensive parts.
So my final recommendation would be, if you can wait for a graphics card, go with intel, otherwise, you won't miss anything when it comes to gaming.
since even if Intel is better in many things, When it comes to just gaming, it's not a bad option by any means to go with AMD. Especially if it's just things like minecraft.
I will let you know though, I bought my parts only intending to play minecraft, now I'm running servers on it.

So when you buy parts future proof yourself, think about what you might do later on, because you might be doing more than just video games, and that is where having intel will come in handy.
