Antwoord op "Is there any possible upgrades for this computer?"I had added an EVGA GForce GT610 to mine. Just make sure that your power supply is at least 300 Watts. I finally retired it this past weekend. I had also upgraded it with a 2TB hybrid drive, and I had placed 4GB of RAM in it. A 32 bit OS is not able to see more than about 3.5 GB of RAM so it's recommended for you to install a 64 bit OS.
