I'm looking for a desktop which runs recent games at medium to high settings and costs about 600$. The specs should be like something along the lines of the following:
CPU: 3GHz Quad Core
Furthermore, since I don't want to spend too much money on power, I would like it to be quite efficient, preferably with a wattage lower than 250/300W if this is possible, given my other requirements. I found this excellent 600$ build online but the wattage was far too high (400W-ish). Any suggestions?
