is UD3P Rev 1.0 still very good compared to Rev 1.6? also does the NB get hot like in RE that you need to cool with a water block? i'm thinking of getting rev1.0 but can't decide if i should look for rev 1.6. is buying a used rev1.0 for 75 shipped good idea or should i be getting a new rev1.6 from egg at $110 AMIR. i already plan on going water with my cpu. so i''d figure if the NB gets hot, i can just throw on a MCW30 on it.
