Since you don't appear to have gaming as your main priority, i would suggest the Radeon 5770 card. It is cheaper than the 6870/6950, doesnt perform as well, but is a solid mid range video card at the moment. Plus it will save you some cash.
Also the RAM you mentioned looks good. You probably don't need any more than 8GB's of RAM at the moment.
