Not sure where you are in the world, so I'm using Newegg. Find these models on sites where you live as appropriate.
Newegg.com - GIGABYTE GA-970A-UD3 AM3+ AMD 970 SATA 6Gb/s USB 3.0 ATX AMD Motherboard
<~ Motherboard I would use instead
Otherwise, the rest of your setup is nice. The motherboard should save you about $35, and sets you up for future CPU upgrades from AMD, assuming they ever sort the issues with Bulldozer out. The chip you picked is fine (I own its older brother) and will do fine in games and other tasks.
Overall, you've got a nice setup. If you want to add a third party heatsink to your CPU, as the stock unit on the Phenoms can be a little loud sometimes, I highly recommend the Cooler Master Hyper 212+. I use one on my 1100T and I just bought one for my brother's system and it was $26 shipped. Easily one of the best deals out there right now.
