[ubuntu] NVIDIA G64 GPU Driver Choice

Hi, I'm ruing 14.04 lts on a 64-bit AMD desktop. The NVIDIA G64 GPU has been ruing in this machine for a year or more. Throughout that time, I was using the built-in X-Org graphics driver and all was well. But there must have been some update to it, as things changed. I use Psensor to monitor my CPU and GPU heat levels. CPU is always around 30 C. GPU was ruing between 60 to 75 C. But recently, it started spiking up above 90 C. I went into Additional Drivers and switched to the top one listed, NVIDIA driver v. 340.96 (proprietary, tested). Psensor immediately showed the temp dropped to the low 70's C. I didn't even have to restart.

I'm posting this in case anyone else has this problem, or if I've mis-interpretted the above, or if there's a bug in a recent X-Org update.
