depends how many layers and what you are doing with them. Since XP pretty much needs 256mb to run, 512 isn't really enough ram for any serious photoshop work.
1GB of ram seems to be pretty standard for most people doing any kind of graphics work, particularly if your multitasking.
Photoshop/3dsmax/blitz/outlook/IE etc
Which I run pretty much continuously all day long, use up quite a big chunk of ram.
