I have a surplus of Dell XE3 SFF PCs. They come with an R5 430 card. My daughter plays Genshin Impact and apparently this PC can't handle it. The R5 430 card takes the only PCI-E 16X slot on the MB. I have a free PCI-E X1 slot. If I use a riser adapter card with another R5 430 card, will she be able to play Genshin Impact? I also have an HD 6970 2G GDDR5 card (much bigger card) that won't fit in the case but can connect via the riser adapter card. Would this be a better choice?
