I have a HP Pavilion 550-a114 Desktop computer. The motherboard uses AMD integrated graphics and I want to get a new graphics card for better fps in the games I play. I would be happy with just 150 fps or more. Does anybody have any reccomendations please, I've looked everywhere and no luck. Also, could I possibly use a graphics card as an external GPU for my desktop similar to using an external GPU for a laptop??
