The renewed computer has an i7 processor.  I use the computer for day trading equities using six-24 inch monitors.  If multiple jobs are needed, it will be necessary to upgrade the 8 GB RAM to 32 GB and it will handle just about as many tasks as are needed.  I had to install an AMD 7750 EYE 6 graphics card to run the six monitors and the power supply has so far handled it well.  The Optiplex has been superior to buying a new computer and this is the 5th one I have purchased over the years.
