ATI tool should tell you. If you already dont have it it is here: http://www.techpowerup.com/atitool/
Then click on "settings" and a few lines from the top you should see "chip name", mine is an r420.
I also have an x800PRO and its on stock cooling. It has never gone over 60*C Core temp. It usually never exceeds 55*C. I get a stable OC to 540 Core and 605 Memory. I used ATItool for a while, then I saw that ATI Tray tools had an overclock section that let me overclock by about 20 MHz more on both memory and core.
Good Luck in overclocking that thing, it has been good for me
. Let us know how that cooler does for you, I am interested in getting one myself.
