First thing I notice is that the MB supports CrossFire while your GPU has a NIVIDA chipset. Not a big deal unless you might want to add a second GPU in the future, in which case you would want a MB that supports SLI or a GPU with an ATI chipset.
I'd also go with faster 1066 memory. If you can find a pair off the
QVL List for your MB you're assured of good compatability.
Buy your PSU and case separately - You'll get better PSU quality. Get at least a 500-600W PSU, (or more if you don't want to replace it when you upgrade)
Pick out an ATX midtower or fulltower case you like and pay attention to number of fans. Good airflow is essential, but too many fans and you may not like the noise generated.
Lastly, pick out a good aftermarket CPU cooler, (the stock cooler won't handle overclocking)
Take your time and read the manuals when assembling. The best part is when you punch the button for the first time and it actually works.
