They will probably install and run, but also, probably, with deliberately
cripled performances.
A dirty trick by those making the demos (independent from where they come from):
Let install on the concurent maker's card, but disable some features and replace
others with some DEoptimised versions that deliberately run slower.

To get the real results, you need to use demos and benchmarks by independant
devlopers, and hope that your drivers don't have special codes that lowers the
settings like resolution, polygon count and colour depth, to artificialy make
the benchmark run faster. nVidia DID use that dirty trick, and there is no proof
that ATI used it or not at this time.
