Thatq VidCard ain't worth it. Get a eVGA 6800, its much better and if you want you can overclock it to the 6800GT.
If your not going to overclock don't get that RAM. Just get some basic ValueRAMfrom Corsair or something.
If you are going to get a 3700+ I would recommend getting the San Diego core.
I have never heard of that Motherboard. Soem reliable companies i would buy from are: DFI, MSI and GIGABYTE.
Thats my advice.
Gigabyte EP-45 DS3R
e7200 @ 3.2
Corsair VX 550
