X800 overclock, too hot?

[Clearion]

I've reaced 435Mhz core and 415Mhz memory clocks with my Sapphire X800, but when i go higher it gets unstable an ATITool finds artifakts, i've noticed that the core is at about 70C when i run artifakt scan or 3Dmark, so i think i could reach higher with better cooling than the original, but i ask, is it worth it, how much higher should i be able to go with, say, zalman's Fatal1ty cooler?

zalmans fatal1ty cooler is nice! depends on the card, try it though. it should overclock higher, it uses 110nm tech, most cards use 130nm tech. it should put out even less heat than most cards.
i say if you can play the games, then you dont need to overclock. lol as long as fps stays around 60 or more your fine. also use omega drivers for your radeon card!
