Moar is better... of course...
Dice is fun and a GREAT way to start, but considering you were subzero before dice....
I went from rad out the window in winter (sub zero celsius of course not F) to Dice and then to LN2... WOW... It is a rush. Did not keep my dewar, but figured.. I can only afford to get 160L at a time anyway...just need to move my bench closer to outside
Have fun in your endeavors...
The strength of AMD is in numbers... you can buy 20 AMD chips for what 2-3 top level intel ones do...(plus cheaper everythign else including power supplies and electric bill :p )
Basically design for LN2... might suffer a little on DIce... but you will go LN2... you will find it for $1 a liter or less.. might take 12 months but you will and on amd there is no reason to limit yourself to DIce.
