Much thanks to Mr. Linuxfan for all the help on ocing my 5870.
Got a few good scores and some nice global points.
Particularly 3DM01SE @ 104737 is not too bad.
I did most of this with the back door open into the room.
Outside temp was as low as -4C.
Inside I measured as low as +14C room temp.
Painfull at times - but looking back - perhaps worth it after all!
