AMD ups the Game to 3 for Quad Cores and Crossfire

This may be old news for people, but there's a little bit more than meets the eye. AMD at Sunnydale on July 26th revealed news about their new cpu and gpu technology. Dubbed "Phenom", the monster quad core had a bus speed of 3.0ghz (yowzas!). The other neato news from AMD was the Phenom powered rig showing 3 HD2900 cards in Crossfire. Talk about some serious firepower, although the HD2900 has been quick to fall behind the 8800 series, 3 cards in Crossfire might be enough to surpass a pair of 8800 GTX in Sli.

There's a little bit of confusion here upon viewing the Phemon Rig. After hunting around I learned that the third card in Crossfire will be used to compute JUST physics calculations. I noticed this when this when there was a apparent lack of another Crossfire type dongle shown below. The effects of having one cards devoted solely to physics are unknown but it is sure to improve performance somehow.
What this means is that it's not truly splitting the load equally amongst 3 cards, it's two cards in crossfire with a third working on something else. This will probably take a lot of work off of the other 2 cards which would be ideal allowing the other 2 cards to work on other tasks. I'll have to rummage around for more info on this but I'll keep you posted.
