Athlon 64 4000+ to Dual Core ? worth it

[spinna]

ive currently got a Athlon 64 4000+ CPU and ive been looking at getting a Dual Core since they seem very good. but..
is it worth me upgrading or should i just wait a while?
if i did get a Dual Core CPU what one will give me a better performance increase over what ive got now?? (im not intrested in overclocking )
and with AM2 Processors just comming out if im gonna get a new CPU shall i go down the AM2 path because it will be more future proof with it using DDR2 (how much faster is DDR2 over DDR memory any way?) it just means i will have to buy a new motherboard as well
shall i just save my money and wait for vista

i play a lot of games and use winrar a lot you know that sort of stuff converting films etc .

to be honest i just surf the net (OCUK )when in doing some thing like converting a film or burning a disk so there is no worrys there .
and if im playing a game i try not to have anything going on in the background anyway
