Hi, i currently have a Dell Dimension c521 (specs here: http://www.dealtime.com/xPF-Dell-De...p-Computer-Athlon-64-3200-2-00GHz-160GB-512MB). I would like to replace the stock graphics card, a NVIDIA GeForce 6150 LE, with a Radeon HD 4870 1 GB

I believe they both use a PCI express interface, but is that enough to tell if they are compatible? Additionally, does the Radeon HD4870 require a power supply of its own?
