The temp. has not exceeded 57C after 2 hours of Bioshock on high settings and a 3DMARK sore of sm2.0-2412 and hdr/sm3.0-2032.

How much further should I try to push this thing?

Is it best to OC the core first, then after artifacts decrease by 10 and leave it while you OC the mem or should you put the core back to factory setting to OC the mem, then put both on the max minus 10?

Also, ATITools will not work and neither will Rivatuner, only nTune is able to OC the card, so I am unable to run the scan for artifacts in ATITool unless anyone knows how to get it to work with my card...What should I use to check for artifacts? I have been running the 3DMARK 06 test over and over then playing Bioshock on max setrings and have not seen any artifacts.
 
So, maybe 55*C was wrong. I was able to use ATITools finally and it is reporting aroune 70*C, now I have no idea which one to trust.
