Thanks for taking the time to answer. I thought I knew something about computers until I read some of the stuff in these threads. I was quite impressed with all the knowledge everyone has on this site........way above my head.
I always like to upgrade whenever possible but with all that I have been reading, I am not sure it is a good idea right now. Seems like there is always some type of problem with Nividia and their drivers. I did update it once and it was fine except I spent some time getting the sound back. I have a pretty good setup and enough ram that I think I will just leave well enough alone.
