Is my PC Good?

I suggest upgrading your CPU to an I7 Processor 7700k or 8700k but your RAM and GPU are completely fine. I know that CPU are expensive but a better one will go a long way.

HAHAHAHAHAHA GAME GOOD BRO. AND NVIDEA? HAHAHAHAHAHAHAHA

You have a really nice pc but u need an i7 i think.

Yes this PC is perfect ! With this PC you playing all games on the world.

It's a decent build that should be able to run games on medium with 60+ fps.

I have GTX1050 too. But not all games fluent. The Evil Within 2 is stuttering in 1080p Low setting. I'm playing with Ryzen 5 1500X CPU & 8GB 2400Mhz RAM. Assassin's Creed Origins stuttering too same system (Low 768p). Forza Horizon 3 only playable on 1080p Low settings.The VRAM of this video card is very low for newer games.

Good for what?
For basic use, yes your pc is amazing..
for work? depends on what you do for living..
Gaming? no, you should upgrade ur gpu and memory at least..

you have a great pc sales better than mine, and I'm not complaining about my own)

Having a PC is already being pretty blessed. But compared to a good gaming pc it is pretty bad. It is an ok pc non the less, and you will be able to run most games.

Pretty nice specs, good for new games, like DOOM (haha new) and etc.
