After seeing the news on the new EVGA X58 LE board I'm getting interested in that. The only different seems 6 phase analog PWM vs 8 phase analog PWM.
What is the downside of having 2 phases less if it would be to go 4.0 - 4.2 GHz i7 with watercooling?

I know it's a bit soon seeing it would only come out next month, so reviews aren't out yet. But any info would be nice about that phase change.
