GPU's are far more efficent at doing physics calculations then cpu's ever will be. GPU's have massive amounts of parrallel proccessing power. Its a neccesity as thats how you proccess graphics. It turns out that physics proccessing also works best on chips designed for parrallel proccessing. A CPU isnt designed to process things in parrallel. It can do it but i involves using much of the cpu's resources and involves long circuit paths through many transistors, ultimately slowing any physics output and chewing through the cpu's resources.
Anyway reports from some sites i have read indicate that you could soon use an oldish gpu card (8 series and above) as a dedicated Physics proccesing unit. That means you could possibly use your old 8600gt for physics while you brand new GTX280 does all the graphics on an SLI board. This isn't just good because old cards retain value and usefulness. It indicates that nvidia could also be getting set to realx the SLI conditions.
The Triumph proved to be one of the better looking and performing pre-paid handsets we'd had the pleasure of holding in our sweaty mitts, but we had one major hangup: the name.
