just how far can i oc 1 of these cards to im currently at 444mhz/1133mhz ?

the tool im using will allow up to 850mhz/1400mhz surley it cant go that high ?

will i break it trying ?

Of course not.... Try pushing it to 450, then benchmark it, if you see any type for freezing push the card back down. The cards not going to mess up, from o/cing it, it has the core slow down.. so overheating shouldn't be an issue... should be easy to find your limit
