Yes, they would crawl. Those are very slow computers for gaming.
You don't really have any options aside from buying a new PC or paying a bit of money to upgrade.
The 1.6 P4, with a better video card and another 512MB ram (to get it to 1gig) may be able to run OK.
The games should have minimum specs listed somewhere, if the 1.6 CPU is too slow, I would not even bother upgrading the RAM and video card. You can get a much faster P4 system for a $100 or less on craigslist. If you do want to upgrade....
I'm assuming you have an agp slot in that thing and if you have full-size slot you can get something like this: http

Maybe check craigslist or ebay for some used parts. Although if you go ebay, watch out for shipping costs, unless it's free, you can end up paying 2x for something due to that.
