I have a P4 3.0 GHz with IMB RAM, and genuine Intel Motherboard. Previously I had RADEON 9600 XT (256). Yesterday I switched it with a Club3D NVidia GeForce 6600 GT (128). I thought the RAM was an issue, but their would be substantial gains in performance as the new card is two generations ahead.
After installing the card, I fired up Far Cry. I found that many video settings were disabled, and when I started the game it looked as if it was running on a 10-year-old card instead of my new (and expensive) baby. There were a lot of blank areas in the level. After 2-3 minutes the monitor shut down and then so did the PC.
I re-booted, reinstalled the drivers and then tried to run Half Life 2 and Tiger Woods 2005. While graphically they were impressive, the compute again shut down within 3 minutes.
I am going crazy. I thought paying more money for my graphics would bring me happiness - instead it has reduced me to tears. My 9600 XT performed admirably, and ran Far Cry with all settings cranked up, albeit at 800X600, with perfectly playable framerate. I switched because of the outstanding value for money 6600 GT seems to offer.
Please help me guys.
