title: Table with a lot of columns
body: <p>If my table has a huge number of columns (over 80) should I split it into several tables with a 1-to-1 relationship or just keep it as it is? Why? My main concern is performance.</p>
  
  <p>PS - my table is already in 3rd normal form.</p>
  
  <p>PS2 - I am using MS Sql Server 2008.</p>
  
  <p>PS3 - I do not need to access all table data at once, but rather have 3 different categories of data within that table, which I access separately. It is something like: member preferences, member account, member profile.</p>
