I like the RIIE a little more than the P6T, but both boards are pretty much at the same level, performance and overclocking wise. The RIIE has some more options and gimmiks, but I don't really need them. Price difference right now is 60 Euro.

What makes it kind of boring is the small margin between completely 24/7 stable and max clock. Even when going from air to extreme cooling =/

6.5 GHz looks way more impressive than 5.3 GHz ^_^
