There are a couple of key differences between the Sapphire Toxic HD 4870 and the Vapor-X HD 4890. One key difference is the Toxic card has heat pipes on the card leading out of the graphics chip and the HD 4890 card does not. The card itself shares its cooling design with the HD 4870 Vapor-X card as the chip is basically a higher clocked 4870 and not much else.

The cooler on the graphics chip consists of the Vapor-X plate, a heatsink covering the plate, and the aluminum heatsink/fan combination covered by a black cover. The top of the cover has an S logo that glows when the card is in operation. The fan itself is a large 9 fin fan. The heatsink behind the fan is similar in design to the Intel CPU cooler heatsink.

The top of the card has two bridges for ATI CrossfireX. Installing a Crossfire system is a simple matter of attaching the Crossfire bridge cable between two cards and then attaching another cable between two further bridges. This daisy-chaining works well with up to four cards installed on a motherboard. Keep in mind a couple of things if you want to go the 4 HD 4890 2GB route. 1. Windows 32-bit can only address 4GB of memory at a time. 2. Your system may have less than 4GB of memory and not be optimized for 2 2GB cards much less four even if you have Windows 64-bit.

The rear of the card has the power connectors. While the HD 4870 card from Sapphire has two 6-pin power connectors, the Vapor-X 2GB card has an 8-pin and a 6-pin power connector. Sapphire says that a 500W PSU is required to power the card. The rear of the card also has a metal heatsink with the Sapphire logo covering the VRM. The back of the card has an L-shaped heatsink covering the extra memory that is on the card. The I/O on the card consists of a HDMI connector, a DisplayPort connector, a DVI connector and a VGA connector, offering the widest variety of monitor connection options on the card.
