Solved: Time To Go 7 Years Old And Way To Slow

hello
my pc freezes too ofter and i have to reload xp and all that nightmare that goes with that but mostly it's too slow.
time to get a new one. probably just a tower for now.
i don't really know what specifications to look for (speed is my main concern i never use a lot of disk space anyway.
this is what i found in control panel under system.
XP Home version 2002 service pack 2
AMD Duron Processor
902MHz , 304 MB of ram
would even the cheapest pc be very superior to this since mine is about 7 years old if not what should i look for?
thank you for your help
