One thing to keep in mind, some mobo's don't like 4 sticks of dual channel ram. I didn't know that when I tried to get 4 sticks of Corsair Value Select ram to put in my DFI Lanparty UT nF4 Ultra-D MOBO and it told me to go to hel. It required the ram to be downclocked or be run in 2T mode which is also a performance drop. If you ever plan on upgrading your ram I would say you are much better off to pay the extra now to get 2x1gb of some decent stuff like G.Skills or OCZ. Stay away from ValueSelect if you ever plan on OCing (which you should because you get MUCH more out of your system with very little effor and much less cost)
Also I am a fan of NewEgg. That was just my 2 cents, I think you got a good idea of parts from the other people, however I would recommend looking into an Opteron for Overclockability. My 3700+ San Sandiego is also nice for a lower cost CPU. I am going to try to hit 3ghz with it when my new ram and cooling arrive this week. More likely will get around 2.8 or 2.9 though
Edit: I recommend:
PZERO has the same stuff and has gotten a good OC from it, mine should arrive tomorrow or the next day then I will see how high an OC I can get.
Edit2: Your 2 linked rams seem fine, I prefer 2 gigs if possible simply because games like BF2 and FEAR eat it up like candy. I had originally ordered some OCZ Platinum ram but it came DOA and I also found out that it didn't OC that well so I RMAed it and got the G.SKILLS instead.
