A real headache to chose the right one.

I hear UD7 rev2 power module are re-designed & it has enough power.
So you do not need worried about phase number.

I tested UD7 rev2 under LN2, it's very stable & can pass over 6.0GHz many benchmarks.
I think the stability is almost same as REX3.
But a little bit slower memory speed than REX3.
So it's not good for Pifast & Super PI.
Especialy SuperPI 32M is very slow, almost 10 sec behind than REX3.
wPrime is no problem.

If you have chance, try UD7 rev2.
