Hi guys, I have a HP DC7800 Convertible Minitower: 4GB DDR2 RAM, Core 2 Duo E8300, and integrated Intel 256MB graphics, I want to play some games like The Legend of Zelda: Twilight Princess and other Dolphin emulator games, I want to buy a graphics card that's under $100 and can play at 100% speed dolphin emulator games for the GameCube and Wii, I've seen the GeForce 8800GT but I don't know if my computer supports it. Please suggest me a graphic card that's compatible for my pc and supports these dolphin games at 100% speed. Thank you,
