Coldplate increases the efficiency of your cooling setup, you can run the peltier on the die but the coldplate helps...

if you are running just a water block then no a cold plate really isn't all that necessary, but if you use a peltier, then yes a cold plate is really necessary...

a cold plate help not only to transfer the cold more effeciently but also it stabilizes the temps from the coldplate to the cpu much much better then just a peltier... while a peltier can suffer some fluctuations in its thermal output, the coldplate can really be benificial in helping to keep those temps stable...

now as to material: i would recommend silver if you can get it... otherwise copper will be your best bet... 1/4" to 3/8" thick is good too...
