I have overclocked my x800gt to core 533.25 & mem 553.25, the card works great with no trouble, i have a zalman zm80d-hp noiseless cooler on it....has anybody got any suggestions on how to keep the core cooler as it sometimes reaches 70 deg c.....i know that its overclocked to the high end for this card but this is the only way i can get the best performance out of it for nfs-mw, quake4 & bf2
