In terms of performance figures for the notebook, the norwegian website ITPro managed to run a 3DMark06 bench with a score of 17,000. Kinc from XtremeSystems hit the 20,000 mark in the same bench by overclocking the CPU. He also noted that the Mobility Radeon 4870X2 was running at clocks of 600MHz/1800MHz. Currently the flagship mGPU solution from Nvidia is the 9800M GTX SLI (112SP x 2) and this notebook should easily claim the title of highest perfoming notebook (gaming) as next week rolls in.
Also looks like the Mobility Radeon 4850 and 4870's are going to be released soon (I didn't see a definite release date, though. If anyone finds one, be sure to link to it!)
