I am looking to upgrade my current graphics card but I don't know too much about computers to make a decision. I am mainly looking for something not too pricey that would allow me to be able to run games like Rainbow Six and AC Odyssey at a decent framerate with decent graphics. My computer is a standard HP Pavilion 500-027c with AMD A8-5500 (3.2 GHz), MS-7778 (JasmineR) Motherboard, Radeon HD 7560D Graphics Processor, 8GB RAM, running Windows10 64 bit. It only has a 300w power supply though. Any help is greatly appreciated.
