Worked great right out of the box. Saw lots of different reviews on this. I assumed a lot had to do with the seller. I paid extra to go with my seller TekRefurbs as they had the best reviews. I had a question for them and called tech support and got an pickup immediately. I asked if the computer could run two monitors at once.. He said yes but i would need a hdmi convert cable which he overnighted to me free of charge. I was so impressed i ordered another Dell Optiflex from same seller yesterday. They were out of the 7010 so i bought a 990 instead.
