A 6950 would do fine. SSD is fine as well, though you really don't need to upgrade the hard drive if you don't mind stuttering a bit in org/IF while the textures load. You'll love it to be sure but if you're trying to save money, I'd probably just grab the video card and see how that goes for now. If you get really annoyed with lag in org/IF/etc. then you can upgrade the SSD later. You might be surprised at how well it works with just the new video card.
