Yep, that will be a sweet setup. It will have more than enough power to handle anything you can throw at it from TGC software. My specs are in my sig, and I have a very similar setup.
It's very satisfying when your computer can handle what YOU want it to do, instead of the other way around. I learned that some time ago, to buy the best possible components you can afford instead of trying to get the best deal you can with "budget" parts. Then you can sit back and enjoy a rock-solid, reliable computer that doesn't limit you in what you want to do.
