I'm currently assembling a PC which can only cost 800 euro (my mother does not allow more) and since I can only spend 300 euro on a graphics card, I decided on a gtx 970 is that still a good gpu? (For minecraft, pubg, fortnite, word of tanks)
The card may be enough for your mentioned games, but there are better ones…
The rtx 2060 shouldn't be that much more expensive… And it's much better…
Honest?
No, that's a waste of money.
But what else can you buy right now?
An RX580 8GB, but they are three times as expensive when used.
Get a used 1050 ti for the transition
Right now is the worst time to buy a graphics card.
In itself it is still worth it. But for 300euro you will certainly get a 1660super / 2060. They are both much stronger than the 970
