I've got a pair of NEC Versa LXi laptops that were once decent computers. They're both P3-450MHz Intel CPUs, with 256MB RAM, 8MB integrated video systems and 17GB harddrives. They run 2000/XP very slowly, and I'd like to upgrade them a little (if it's worth it) to speed them up -- problem is I have no idea what to upgrade. They seem to be thrashing around on the harddrives a lot... so my initial thought is new harddrives for them. Are them some benchmarks I can run to determine what is the slowest link on them now? If so, what should I run? Thanks...
