Hi Greg,
I've put together a basic list which you may find useful starting point:

you would just need to add about $450ish for the graphics card (the prices aren't listed yet on this website but I've seen that model for $429).
of course you can choose more/bigger storage etc if you feel like it.
the psu is of high quality and realistically you could get the lower 650watt if you felt the urge.
After thinking about this thread, I actually went out on the w'end and doubled my Ram to 32gb and grabbed an extra 2tb storage.
