The first photo's of CeBIT already are becoming live. Spotted at MSI's booth the R7970 Lightning, the Tahiti-based graphics card uses a big PCB, 14+2-phase digital power, a Twin Frozr IV dual-fan heatsink, and something called a GPU Reactor.
The Reactor Core is seemjs to be an add-on PCB that has several tantalum capacitors. Next to the capacitors, there are blue LEDs and a round window that seems to lit up.
The card's clock frequency and pricing ... and release date are TBA.
