Here's a slightly upgraded version of the Dell Optiplex 390/790 with an Intel 2nd Gen i5 2400 (or better) and instead of a 500GB HDD you get a 240GB SSD which is much faster! You also get a Radeon R5 240 1GB which gets about 3-10FPS higher in most games than the GT 710 1GB. 2 display out options: DVI and Display Port. DVD drive and hard drive cage may not be included. WIFI not included (we recommend using the Ethernet port but USB WIFI adapter can be purchased separately).
