Oh I can have a field day bashing this one. It supports BOTH SLI AND CROSSFIRE! WHAT DONT YOU GET ABOUT THAT NOOB?!
That makes sense, the R600, due to some current driver upgrades, NOW COMPETES WITH AND SOMETIMES OUTPERFORMS AN 8800GTX!
If it overclocks well. EVERYONE who overclocks will be able to take advantage of that because they can have a board with great features, and a good overclock all in one. Even if it outperforms water cooling, try chilled water, push it farther. You see, the point to overclocking, IMO, is it's like a hobby, and you see how far you can push your hardware, and your pocket book. YES, it get's expensive, but you have to admit, a Q6600 at 4ghz with good temps doesn't sound to shabby, no?
As of x38 support both crossfire and SLI, that is a speculation. However, nVidia did OFFICIALY denied this possibility. Honestly, I think it is very possible for x38 included SLI in their feature list otherwise there is market room for x38 (if it is 30% more expensive).
Like I said earlier, overclocking is not going to be the main marketing factor for x38. At least not until the new 45nm Penryn core. Why? Because P35 can easily overclock above the thermal dissipation of most air and water cooler. As of Peltier cooler, they are not much better than a good waterblock since you have to cool both the heat from the thermoelectric effect and CPU. Not to mention that it suck a decent amount of wattage from PSU. So, the ability of OC higher than current P35 may only benefit those with phase cooler.
