I'm not that good with computers so sorry if this is difficult to understand.
I currently have two AMD HD Radeon 5670 GPU's with crossfire connectors on it. I have 8gbs of memory. I have an Intel i5 core processor. I am trying to play games like Overwatch on my computer. What GPU's are compatible with my computer and will run games smoothly?
I attached two pictures that show the inside of my desktop.
Thanks for any help.
