I'm not sure why you would have to get a NB water block (if that's what you're saying). Do you have poor case airflow or something that can't be corrected? Many people have taken the stock heatsinks off and replaced the TIM with something a little better but, overall, if you have good case airflow you don't need to do anything with the chipset heatsinks - the stock ones are fine.
I'm not much of a fan of MSI but almost any 890FX chipset board from ASUS, Gigabyte, or Biostar should be good. ASUS makes another board, the M4A89TD PRO (also comes in a USB3 version), that is a very good 890FX board. Gigabyte's 890FX UD5 is a good board as well but, of course, doesn't match your color scheme. Biostar has a good 890FX board on the market that has been performing pretty good, too ...
