Hi, I am totally new to the world of graphics cards, and upgrading computers. I have a dell dimensions 2400 series computer. I just bought a GeForce 5500FX graphics card (PCI). The graphics card I am currently using is a intel (R) 82845G/GL/GE/PE/GV or intel (R) Extreme, and it is intergrated, which I am not to sure what that means. I need help installing my geforce, and also I need to know if this card is going to be compatible with my motherboard.
