So I have absolutely no idea where to begin with hardware, software has always been my thing. And as such, I don't really know what to do with this. I paid £300 for my PC and when I got it I found out that its graphics card is terrible. It runs some games relatively easily but most of them require the lowest possible settings and even then I get under 15 fps and massive input lag.

The card is a 2047MB NVIDIA GeForce GT 710
If anybody can help me with finding a better graphics card and installing it I would be incredibly grateful.

Please Help.
Thanks !

I didn't find the right solution from the internet.
