AMD's ATI Hybrid CrossFire Sneak Peek

@ 2007/12/13
Hybrid CrossFire is not meant for the enthusiast, but we do think the technology will indirectly benefit enthusiasts in the future, hence our reason for talking about it. That and Hybrid CrossFire is just pretty darn cool technology. Hybrid CrossFire is achieved by utilizing one of AMD’s new integrated chipset GPUs (IGP) and one of their new video cards. That’s right; Hybrid CrossFire utilizes one video card plugged into your PCI-Express slot and is able to join forces with the GPU built into the motherboard chipset.
