*sigh* Hit a new snag. I was just settling in on a possibility when I noticed the system requirements included a minimum wattage for the power supply. Checked Dell's info and it turns out the XPS B has a 200 watt power supply... And all the nvidia stuff I've been looking at requires at least 250 (some 300 or more).

There are some ATI cards that look possible... but I haven't seen power supply requirements listed at all for them. Most sites don't seem to want to bother to include that sort of thing.

Guess I'll have to do a bit more research.

When in doubt, think about penguins. It probably won't help, but at least it'll be fun.
