Well, everything went very well and running much cooler. The board in particular runs a whole lot cooler under load. Also comes with some solid software that makes things like speedfan, etc, unnecessary. UEFI is also really great - coming from someone who has only used BIOS before this.
Very impressed with ASrock. I spoke with a friend in Japan and he says that is pretty much the only motherboard option there. So it looks like they went from a budget option to an enthusiast option with significant shares in some important markets.
Most importantly, the games I am playing at the moment are not optimized for more than one core so I'm seeing some impressive performance increases in those games, over the i7 920. Around 30-40 fps and they run much more smoothly, overall. Finally able to take advantage of SATA 3 and PCIe 3.
Thanks for the help.
