Adobe Suite Workstation

I'm looking for a sanity check on a build for Adobe suite work. This includes Photoshop, After Effects, etc.

The idea was to stay around $1,000 for the box. The end user of this machine already has plenty of external storage. I think maybe the video card is a bit heavy but Adobe is going GPU accelerated with a lot of their suite these days so it could be a good future investment and having DX11 support is a plus. I am also in the habbit of recommending 32 bit (4GB Dual channel RAM) systems even for Win 7 just because the benefits don't seem to outweigh the hassle for now. Since it's been a long time since I've actually run a 64 bit system maybe someone can shed some light on the current situation for Photoshop users using the 64 bit version of the suite. Pros & Cons?
