A really crappy emachine that my dad gave me. I played Call of Duty on it and the Sims and that's about the most it could run. Then I decided to be a PC gamer so I bought Team Fortress 2 and a good video card for it. It was actually my computer for a long time until recently I just couldn't take it. I could run the games, but not run them well. I bought Left 4 Dead 2 because I just couldn't miss out on it and I hate that game on the 360 and I installed it and when I started out, the opening cutscene's audio went in and out and chugged. In game I could run it smoothly at low. Once, I had died and I tried changing the quality from low to medium and I almost lagged out. My current computer is custom that my dad built and gave me for Christmas. I don't know exactly all the specs and I'm too lazy to figure them out.
