Does
SELECT TOP 1000 * FROM TABLE
return the same data execution plan as
SELECT * FROM TABLE
?

Thanks.
You can check for yourself. In SSMS, go to Query -> Include Actual Execution Plan
Then run your queries.
e.g. when I run:
SELECT TOP 10 * FROM sys.tables
SELECT * FROM sys.tables
They return different execution plans.
