Newegg has listed up a mining kit that consists of 6 Visiontek Radeon 7950s, and pairs that with one MSI 970 motherboard, a single core Sempron, 4GB of Kingston, and two Rosewill 1000 watt power supplies. Yeah, I'm not quite sure how that works either since that board will only push 2 7950s. I have 5 of them. It does signify that mining has arrived. In years past I have had to educate the video card guys I've talked to about this.
