Although i wanted to build my first gaming pc at the moment it's a little difficult for me to do so. So i was wondering if there were any pre-built desktops that could be recommended that would be able to play borderlands 3. At the moment I only have about $800 -$900 that i can afford to spend on it with the hope to upgrade as i learn more about computers, and get the funds to do so. Any information given would be appreciated.
