Tika: If your Mac works for 10 minutes (when left idle) and then dies, then you just need a new graphics card.
If it works for more random periods of time (and immediately dies when trying to do strenuous tasks) then it's likely an over-heating or logic board problem... you could try upping the fan speeds with some software hacks to see if you can improve anything, but it's probably a lost cause.
