In the PC version, the Radeon7000 is exactly identical to the RadeonVE,
except it only has analog VGA out, no DVI (I happen to have one in my l33t
athlon). This makes things extra confusing, since the Radeon7000 Mac
Edition actually does have a DVI connector and TV-out.

I'm pretty sure that the entire Radeon, RadeonVE and Radeon 7*00 series are
based on the same R100 chip, with different clocks, connectors, ram, and
features enabled. The Radeon8500, on the other hand, has the newer R200
chip, and I think an R300 'Radeon9500' is in the works.

You'll have to remember, though, that even with the nice internal
performance of the Radeon7000, running two displays on one 32/33 PCI card
will definatley be pushing the bandwidth limits, so performance may not be
100%.
