Its cooling off here in Vegas and a warm winters night breeze through the window gets me a ambiant 27c temp inside my case.

I am using Ntune software to adjust the video card clocks to 686/2200 for my benches. I pulled the heatsink to check out mounting and replaced the thick gray TIM with some Zalman thermal grease ZM-STG1 and this enabled a slightly higher overclock, it gained me about 25Mhz benchable.

The maximum memory overclock possible with Ntune is 2200Mhz, to reach higher speeds you can use Powerstrip.

For my benches I did not adjust LOD or any setting in the control panels. I was getting best frame rate on all tests with just loading the driver and benching. No quality changes were made.

Nvidia has made huge advancements in image quality, its drastic and without a doubt Nvidia holds the IQ crown. I have pushed the card to max possible detail in many games, for one Flight Simulator 10 maxed out flying in Las Vegas or NY City was a truely boggling display of the cards performance.
