If you can afford an AM3+ that will take faster memory and also will support the FX-series CPUs (bulldozer and the next in that range).
I have just got an ASUS SABERTOOTH 990FX
you can see my comments on that mobo here https://sites.google.com/site/tecchie2011/home/motherboard
been running that mobo for a week now and it is rock solid running PRIME 95 using a corsair HD60 liquid cooler.
There are many other AM3+ mobos so shop around as there may be some good deals going.
