Yes, they both will be slow because they don't use indexes. However, SELECT statement but with WHERE A + B = vp_A + vp_B will use your A+B index and run faster.
See 'Using Rushmore to Speed Data Access' in the help or at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/fox7help/html/dgusing_rushmore_to_speed_data_access.asp to understand how indexes could speed up your queries.
