I bought this computer to do video editing for teenage basketball players on the nearby reservation.  My Acer lap top with 4GB memory did the job, but this Dell 990 loaded with 16GB memory does it many times faster and makes the job so much more enjoyable.  The improvement in speed is incredible.  The 2TB hard drive is huge, but of course not as fast or as costly as newer SSD drive technology.  I actually had to phone customer service to get Windows 10 Pro to load, but there was no wait time on the call, and they gave 5+ star service all the way.  I would do business with this company again in a flash!  (Blair Technology Group) Being an older model rebuilt computer, the only drawback was that there were no 3.0 or 3.1 USB ports.  So dumping the contents of my laptop into this computer v.i.a. a USB drive was a slow process.  I probably should have wasted a blank DVD to make the transfers.  I basically knew the specs on this computer when I ordered it, and could have done better if I had spent 3 times more.  I am totally satisfied with this purchase, and would highly recommend this company.  I saved their contact phone number, and if I need something more in a computer for family or friends, I will be giving them a phone call.
