Does keeping the text field in a different table help performance?

I am working on a website system that has page content in text fields, some of which are quite big. I keep creating seperate tables for the text in the hope that it will improve performance. The reason being that the main table is scanned and filtered a lot.

Does SQL server keep the text content seperately anyway? Am I gaining anything using this approach?

Depends on the text in row setting. Look at sp_tableoption
Look at text in row in bol.

Cursors are useful if you don't know sql.
DTS can be used in a similar way.

So by default SQL Server keeps blob info in a seperate place. So by creating seperate tables like (Page,PageContent) and joining at query time, I am gaining anything in performance?
