new system advice please

[jasylum]

Ok getting a new system and need some final advice. Firstly I am going to water cool it and would like to overclock it so that I can get the best out of the system. Have been considering the following cpu.s X2 dual core 4200 or opteron 170. My questions are

Which one will give the best overclock and maybe even 4800 speeds

Which motherboard and memory is the best for overclocking. Have been reading about dfi boards but advice would be appreciated. A passively cooled northbridge would be nice. Also not overly expensive ram as going to put in 2gb

What is the best case psu combination available for quiet operation and overclocking.


Thanks

Thanks for the advice. Graphics wise was thinking of going the nvidia route but will see. One more thing anyone got advice on a case with a window so I can see if my watercooling leaks etc

Thanks
