I'd have to say that I am very pleased with the RD600 thus far.
1. I have been able to clock over 400FSB (could not do with my 680i)
2 I can run my RAM at specified speed of 1067MHz & 5-4-5-9 2T timmings or 925 MHz & 4-4-4-8 1T timmings (could not do with my 680i). I had to clock my RAM down to 800MHz & 5-5-5-12 2T timmings on the 680i.
3. RAID WORKS!!!! This was never completely fixed while I had any 3 of my 680i boards.
So far this is what I have:
CPU Freq: 435MHz
CPU Vid: 1.42500V
CPU VTT: 1.39V
NB Core 1.2V: 1.48V
NB PLL 1.8V: 2.03V
NB PLL 1.2V: 1.38V
NB PCI-E 1.2V: 1.34V
NB Core 1.2V convert from: 2.14V
SB Core 1.2V: 1.34v
Clockgen: 3.40v
CPU Core 1/2 GTL REF: 80
CPU Core 3/4 GTL REF: 80
NB GTL REF: 96
Conroe P-State: 8x
