help with partitioning my c drive

[theRealMacoy]

a friend of mine lent me a copy of nero partition magic...

i was thinking of partitioning my drive for the added speed and performance (my computer is lagging a bit these days).

i am not very well versed in the pros/cons of this procedure and could use some advice. i read the current post by pokerloco and TT's reply but was hoping for a bit more info.

i would really appreciate any help with setting up the partition and where to lay out my files (such as, i do alot of downloading and wonder where i should be downloading files into and of course where to put my PT db, etc...).

currently, i have a 30 gig hard drive, 1.8ghtz cpu and use 2 postgreSQL databases with PT.

cheers and thanks for the help,
