I don't think you'll be able to do any real gaming with either, except maybe a few games @ 720p lowest settings possible. If you already have the GT730 you could try it but I wouldn't go and buy one. Here's a little info to refer to-I am planning on building a new PC and due to this GPU shortage, Im not gonna buy a dedicated GPU for now. I am having issues choosing the 'Temperory' GPU for my system.
Should I buy i3 10100 with UHD Graphics 630 or GT730 (GDDR5 ofc) and OverClock it?
