ATI Crossfire setup, im confused

[xbox122501]

I just bought two 4870's and was wondering, how exactly do i hook both of the cards up with a single vga cable. then i started watching videos and there is supposedly a special split Y cable that is able to plug into the two cards and then one goes back to the monitor. Where do i find this cable?!?!?!?

You don't need a splitter cable. You just use the CrossfireX bridge connector to connect both cards and plug one VGA cable into ONE card (the top card). Then turn on your computer and make sure you go to the Catalyst Control Center to enable your Crossfire mode.

This must be connected to the top of both cards:

See, just one VGA/DVI cable

Crossfire supports Dual-Video Setup when enabled unlike SLi, just plug in both Monitors on the top most card like Surgevel said

The Y cable is oldschool crossfire. It just uses bridges like SLI does now.
