Is there any way of doing a count using count(*) over that only counts the first x number of records?

Reason I ask is that a search may return 300,000 results but in reality I want to say if more than 500 returned just tell the user that. SQL is so slow at counting that I don't want it ot count the full 300,000.

Evenif total COUNT is greater than or equal to 500, result of this query would be 500
If count is lesser than 500, it would return real count
SELECT COUNT(*)
FROM (SELECT TOP 500 * FROM YourTable) A
