well 512 MB is prolly what is choking the system down. 1GB is more to XP's liking. maybe you have lots of spyware, bloatware? those bog down ur system a lot.. regular defrag, running a low memory intensive background programs( stuff like norton takes over 40-50 MB, Itunes does the same- since the OS needs 200 MB atleast.. you can see how your running out of memory quickly- will slow down performance.. since your forcing windows to use disc caching/virtual mem. you might have a lot of temp files/ viruses? try running ccleaner/spybot.
Your specs sound OK to me. Not too shabby but not too fast either. Overall XP is a pretty fast OS, much quicker than vista. good luck with linux though
Doubt is not a pleasant condition, but certainty is absurd.
