Easy. Because I don't already have a low-end card.

What I'm going to try to do is to be able to show
the faculty and grad students around here how
easy it is to get a significant performance improvement
by using CUDA as compared to using their normal
i386 or x86_64 processors. The actual performance
improvement isn't that important because even if it's
just a 2X improvement it will be easy to justify.
I'm expecting it to be a lot more because much
of what goes on around here has already been ported
and summarized on the CUDA web site with >=10X improvements.

Then, once I've hooked the faculty I'll get them to buy
a high-end card to get maximum performance.
