OK, since I don't know what your local retailer has, it's going to be harder for me to help you, but I'll try.
That CPU is good.
The mobo is good also, but see if you can find one cheaper that doesn't support crossfire. You won't be able to take advantage of it without a much more powerful PSU.
RAM is fine, but is there cheaper?
Go with a DVD burner, you'll find it handy.
Try and find a WD hard drive with 16mb or 32mb of cache. It's well worth it.
Get a different PSU. Look for one from Corsair, PC Power and Cooling, or Antec.
The video card is OK, but seems pricey. What resolution is your monitor?
