As you're using a single core you may be best off NOT installing SP1 [or Acceleration inc.SP2], as it does seem to upset terrain loading and be an additional cause of stuttering for some people. The only trouble with that is some add-ons require SP1 to function, such as FEX...the vast majority are fine though.
You could try SP1 and if it makes things worse remove it.
