Title says it all. I got a Dell OptiPlex 760 for free. It came with a E7400 and 2gb of ram. I took a couple of other "scrape" pcs and made this monster! I took a burn up motherboard pc that I got for free, cpu was a Q8300 and 5gb of working ram and tossed it in the ole OptiPlex. Took a ancient 128gb SSd that came from a 3rd pc and put that in there. From a 4th pc I took a PNY Quadro 400 and put that in there. Imaged it with Windows 7 as that was the key on the box. Its a very capable general use pc. I tried CSGO, got 35+40fps on high, dropping down to medium settings got 60ish fps. Time spent, 2hrs, money spent ZERO!
Update Took out the ram and replaced with four 2gb stick. 8gb total now.
