Performance issue with selection of data on a table

Select ConsumerID,RecordType,
        RecordData + CHAR(13) + CHAR(10) RecordData
From ETL.Stg_to_PP
Order by  ConsumerID,RecordType

Taken out the distinct, added clustered index on col1,col2 Still this simple select with 300 thousand records is taking 8 sec. I cannot include Col3 as it is a nVarchar(max) column and the data in this more than 8000 characters.

Any suggestions on improving the performance.

Explain plan i know it doesnt show anything:
