I'd change the processor to the E6420. All of the specs are the same as the one you mentioned, yet you get a 4MB L2 cache just like the more expensive processors. Plus, its the exact same price. (This is the processor that I ordered a few weeks ago.)

Also, with the video card. I recommend spending a little bit more money for a Direct x10 compatible card. However you do have a good point that its so cheap, you wouldn't worry about replacing it. But in my opinion, I'd rather get the DX10 card now and not worry about potential problems down the road.
