Last summer we got the third edition , which included 1 GHz ethernet and dual processors. The faster models, with 667 and 733 MHz processors, will be available in February with 256 MB of RAM and a 60 GB hard drive. These will use a new G4 processor with an integrated 256 KB level cache and a 1 MB level 3 backside cache.
Prices are attractive.
The real attraction here is the nVidia GeForce 2 video card. If you're a heavy Photoshop user or work extensively with digital video, this could be a real plus. However, because of the integrated 256 KB level 2 cache, the true speed benefit may be even greater. That's a tough call until we know how well the new G4 performs in the real world, but this looks like a dynamite production machine for Photoshop and digital video. For basic production, we recommend looking at the 466 and 667 MHz models first.
