If waiting for R600 has you down, Sapphire has an upcoming alternative. Early this morning the company internally demonstrated its dual-GPU Radeon X1950 Pro board, dubbed The Godfather. The dual-slot GPU uses two 6-pin power connectors but still fits within the standard 9" riser-board dimensions.
Sapphire representatives tell us the performance of the single card is comparable to two Radeon X1950s in Crossfire mode.

Also visible on the adaptor are the two interfaces needed for AMD Crossfire. We have confirmed that the upcoming adaptor does not need a Crossfire motherboard as well in single-card implementations. However, memos from the company reveal that the card can be put into Crossfire mode with another identical card on a Crossfire motherboard -- the upcoming implementation would be the first capable of Quad-Crossfire.
Expect to see demonstrations and benchmarks of the card during the upcoming CES 2007. Sapphire claims the card will be available in Q1'07, well ahead of the R600 launch. Sapphire recently announced its AGP version of the Radeon X1950 Pro, but the company would not respond if The Godfather would be available in AGP versions.

Se o preço rondar os 300-350€ é uma excelente placa.
O quad-crossfire é que já não tem grande interesse a esta altura do campeonato. 
Cumps.
