I'm not really sure what I would need to look at, or where to find it, but I'm looking for a discrete graphics card to use in my HP 17 laptop with the PCI expansion slot. It currently has Radeon Vega Graphics, and I was hoping to be able to find some sort of graphics card, or something that could be put into the expansion slot to replace the integrated graphics. If such a thing exists, where would I find it, and how would I know which type of card to get?
