9800 Pro Atlantis needs urgent help

[tipsydipsykipsy]

I have had a slight accident with my Radeon 9800 Pro Atlantis graphics card and am hoping someone out there can point me in the right direction and possibly save me a small fortune. Living up to my name, one day whilst playing with the internals of my poorly PC, my hand slipped (don't ask how!!) and managed to catch the small heatsink which sits on the chip on slot Q8 resulting in both coming away from the board...whoops!! The chip has the following code on it (if my eyes are not decieving me H33BB FDS 6912. Is there anyone out there in the big wide world that knows where I might be able to get me dirty little mitts on one and what the cost may be? You are my last hope otherwise time to part with lots of dosh. Cheers
