Katy,

SLI is not a new "feature", this was implemented many moons ago -- long
before FS9.

However, ATI's Crossfire does look very promising with three different modes
of support, 2 of which are completely DX9 compatible. So it looks like I'll
be doing ATI Crossfire in my near future (as soon as the cards are out and
motherboard is available). It'll be interesting to see if Crossfire does
work with FS9 -- if it doesn't then one can be assured the FS9 dev team are
using more of those "undocumented" features in DX9 or the OS to make their
products work faster/better than anyone elses ;)
