hi, i have had my pc for about a year and for xmas i want to upgrade it 
my current rig is:
Chip: E6600 2.4 ghz with stock fan
mobo: Asus p5b Deluxe
RAM: 2x 1gb ocz pc2 6400 Platinum
Graphics: Nvidia 8800 gtx on a 1280 x 1024 screen
Power: OCZ GameXStream 600w SLI
HDD: seagate barracuda 7200.10
Case: Antec 900
OS: vista home 32 bit (would 64 bit be better?)
the temperatures
i currently get never get above 54C cos that the alarm point, but i also rarely use all the fans on the 900. idle temps around 34C
i have this Ai booster which helps overclock, but is it best to change the multiplier or the frequency?
What id like
my plan is to hopefully:
overclock my cpu to around 3ghz (i may need a new cpu fan - which is best?)
add more RAM - any opinions would be helpful
add 2 more 750gb hdd's - i think 7200.10 is good for this
possibly overclock my graphics card - i dont know where to begin with this
preferably id like to keep the cost down as i can then buy more beer
i have considered water cooling but i dont know if it can beat a good fan at the price i want
this would be my first time overclocking a system so any help would be greatly appreciated
