The exact numbers depend on the specific 3rd party implementation of the chipset. For a budget card that is around $100, I'd go with either a AMD Radeon HD 7750 or a NVIDIA GeForce GTX 460. The GTX 460 is a Dual DVI Video Card w/HDMI & HDCP Support. It performs nearly twice as well as the HD 7750. It has no VGA sockets and requires 2 of the 6-pin PCIe video card power plugs, so if your power supply lacks those, you might want the 7750 instead.
