Are they real? We won't ever really know, but the folks at MacBidouille have been known to be rather prescient in the past. However, they are a very Mac-happy bunch, so it might just be propoganda or wishful thinking.
Their latest story contains benchmarks from a series of supposed 970-based machines, including a single-970 @ 1.4GHz seen to outrun the current dual 1.42GHz G4 by about 87% in Final Cut Pro and 112% in Maya.... that'd be nice.
They also claim benchmarks on dual 1.6, dual 1.8 and even dual 2.0 machines.
