The computer was a gift. I didnt really have a choice. Yes it runs doom 3 and halflife 2 and all the major titles out right now. I mainly want the experience of building the system and overclocking. Sooner or later something will come out that my current system cannot run. Considering the fact that I cannont upgrade this computer any further I would like to get a new one. The reason why I posted this was because this will be the first system I havew actually built from the ground up and I had some questions.
