I would get the full system specs and compare them to the list of minimum and recommended requirements for 3.9 (just saying that since you seem to not know exactly what is installed).

Also someone else just posted a similar thread on this yesterday: http://www.amiga.org/forums/showthread.php?t=72504

Some good info in there already. Good luck!
