So i have a friend of mine that i heard talking about a game he got in a package called the Orange Box. It comes with Portal, Team-Fortress 2, and Half-life, with episodes one and two on it. It sounded interesting, so i bought myself a copy. I can play portal and half-life, but i cant play Team, its too slow when i join a game. I even tried lowering the settings in-game, but it only helped a little. I have an Aspire 5520-5912, with 2GB DDR2, and 160GB HDD. Would a graphics card solve the issue?
