Don't need a UPS for those.... a surge protector alone would be just as useful (and cheaper), unless you want to have the UPS kick in when an outage occurs so you can save whatever you're working on.
With power outages (depending on what caused the outage of course) RAM tends to be the first thing to die. Download a copy of MemTest86+
and test your ram. If any errors are detected, replace the offending ram stick.
