Hi! so lately I've been having some troubles running the games i bought in the steam sales with my pc (which is pretty old) right now I have a low budget (around 80$) and I've been searching for used graphics cards for my PC, though I'm not a huge expert so I want to know which one should I take based on my budget and my pc build since that I don't want to bottleneck it with my CPU!

CPU: A8-6500
MB: HP 2B17
Ram: 8gb DDR3
GPU: AMD R7 240
I don't know what kind of PSU I have since that it doesn't show anything even by opening the case

My plans were to get a 750ti or a 760 since that theyre still great for gaming and they dont need a powerful PSU
