Hey everyone... I am just getting started with trying to upgrade my graphics card and I know absolutely NOTHING about what I am supposed to look for at all. I have an Asus AMD A10-7800. it has 8GB DDR3 memory (and is expandable to 16 gd DDR3 memory) it has 1TB HDD storage and has integrated graphics (I got all of this information from the side sticker and amazon https://www.amazon.com/Asus-Desktop-A10-Microsoft-Windows/dp/B00WPEM2S2). I am a twtich streamer and I was hoping I could upgrade my graphics to play games like Overwatch, The Dark Souls series, Player Unknown Battlegrounds, and possibly Battlefield 4. I was curious what the best graphics card would be for me to get so my computer will run better and possibly run these games. Any help will be greatly appreciated since I am completely new to this (never done anything to a computer before).
