A video card which is better than a GT 635, is working without bottlenecking an i7-4770, and is not requiring PSU upgrade, I think you may consider upgrading to a GeForce GTX 1660.
Well I want to get a better graphics card (bc the one I have is not exactly the best) and so here I am.The specs are:  Stock 460w psu  Intel i7-4770 at 3.40 GHz  12 gigs of ram (gonna upgrade to 24 gigs sooner or later)  Nvidia GeForce GT 635 I want to get a graphics card hopefully from nvidia but if another company has one that works much better for a similar price point I’ll get that one instead.
Better graphics card for XPS 8700?
