LOL yugi you didn't need to say all that i was kinda gonna say what you siad but theres www.computerlounge.co.nz as well but you could get some cooling and try overlocking....
na i just found out lol that overclocking is bad cos the microsoft technician told me that when u overclock the cpu, after awhile it will blow and u will need to get a new motherboard and cpu so it aint worth it but ill overclcok my graphics card.
i dont noe, maybe u shoudl just not upgrade this computer, its gonna end up costing quite abit if u watn to throw a 64 in there, so mabye get a socket 939 board, so u can eventually make a system out of that
, but otherswise id say get some ram, cuz at least that can transfer to anthoer comp
