AMD released this new series of GPUs back in June and hasn’t looked back since that time – we’ve known this day was coming for awhile and the entire industry knew as well. Today is the official release date of the Radeon 4870X2 card and the reason it’s cool is that now you have a single graphics card which slaps on two GPUs and two gigabytes of GDDR5 memory for what makes up the fastest single card solution available at a price that’s sure to drive NVIDIA to drop its prices on the 280GTX card.

In the end, this means that you can go out today and buy two of these cards in order to run a quad-crossfire configuration. The X2 card uses a PCI-E 2.0 bridge chip to run a seamless crossfire setup on the card that’s completely transparent to the end-user. We’ve seen similar configurations on previous generations of video cards from both AMD and NVIDIA, however, this is the first one from AMD to use a PCI-E 2.0 bridge which provides additional bandwidth for the GPUs.
