Summary: At first my pc didn't start because it is heavily loaded with equip (3 HDs, DVD, Soundblaster) and I only had a 350W power supply. I replaced the Power Supply to 500W and now the GeForce 7800 AGP video card is working like a champ. I tested it with Call of Duty4 and works great.
Summary: This Nvidia video card is fairly decent. It is kind of a mid range component but works quite well. I like the Nvidia products but you have to be carefull when installing the correct drivers. There are a lot of additional drivers and programs that you don't always need.
