my dad went out and brought me a new PC and without informing me - here are the specs - is this any good ?

Your friend is right you should have no complaints whatsoever about the computer that you were given. It's an extremely powerful computer there shouldn't be any game that you should not be able to play very easily. 

For right now you can consider yourself King of the Hill you probably have one of the most powerful computers in your city.  I'm a computer repairman in Statesboro Georgia so I can tell you what you've got you really ought to tell your dad thank you thank you. 

Because he got you a really nice computer

We live in a place where PC gaming is everywhere. ... But here's the thing. My ... My dad won't get me new PC or laptop, I have asked for one so many ... made fun of, this is a old laptop, and I can't play any games or do any ... And I am not even asking for a good PC, only a $350 one with a Ryzen 5 2400g.

I wouldn't be complaining it's a nice PC

all that looks good to me?

I'll laugh when DNA tells you he isn't your father. Thank your dad whether you have the highest bragging rights or not. Put the machine through it's paces and prove it to yourself. In two or three years you'll be whining for more. If I had the chance, I'd tell your dad to make you buy your own computer. Find a way to be productive and not just always playing games.

go elswhere troll , wasting our time . some trolls think your an idiot .

It's a very good PC considering how hard it is to find he 3090, but it was probably over priced.  The 3950X is a decent, but obsolete processor, but that was probably the only one they had in stock since you can't get the 5950X easily.  

A machine of that specification is most gaming enthusiasts wet dream, but so ludicrously expensive few can afford it.

You could likely buy a small car for less than that cost.

Your dad went out and bought you a new computer. The normal response is, "Thanks dad!".

I agree with the first answerer.  This is highly suspect.  You want a "good gaming PC" and yet haven't done the research as to what parts makeup such a machine.
