I needed to upgrade my 2009 Dell Precision T3500 since it was as bit sluggish after upgrading to Windows 10 and thought I'd give this model a try.I've been using this one for 2 weeks and it seems to work flawlessly for my needs.I use it for Office applications, web surfing, video conferencing, AutoCAD and a bit of video editing without any hiccups.Unless you're heavy into gaming, this system is sufficient for most everyday, home/office use.I'm probably going to purchase another in the near future.The only minor issue was the DVD drive's power supply was not connected, but that was an easy 10 second fix.I'd give this product 6 stars if I could.
