I was replacing an older Dell Optiplex system that was still good, but the Windows XP on it was going to become a problem. As a techie, I wanted Windows 7 instead of Windows 8, and Dell offered that on this unit. I don't really push a PC processor very hard, but I do a ton of multi-tasking, so this unit, with a more modest processor but 8GB of memory, fit the bill. Plus, having 8 USB ports (and lots of those being USB 3.0) was a very good thing. Initial impressions have been very good. First off, the unit is wonderfully quiet...a great thing for a PC that I leave on 24/7. It is quiet enough that when I walk in the room, I can't tell until I move the mouse whether if it is screen blanked, or is in Sleep mode! Performance is very good; boot speeds are impressive, and a few things, like video conversions, have surprised me with their speed. Lastly, it didn't come with a lot of bloatware that would be a pain to remove...THANK YOU, DELL! I didn't want the McAfee they loaded (I prefer Norton), but removing that was straightforward. All in all, this was a very good PC for a very good price.
