My modifications to your original build;
1.) Instead of getting the A-DATA RAM, get this
2.) Get a SATA150 hard drive. UltraATA/133 is getting old.
3.) Change the motherboard to either the Lanparty nF4 UT Ultra-D or Lanparty nF4 SLI-DR.
4.) The Liquid Cooling isn't worth it. The stock HSF that comes with the processor is very good, you don't even need another HSF.
5.) Sound card. I see you already switched to the LIVE. Good choice.
The processor is just fine the way it is. Pzero, recommending the 3800+ over the 4400+ is like recommending the 3200+ over the 3700+. If he has the money, he should go with the 4400+.
