Downloading and installing now. Will post results later when I get home from work. Also eVGA released a new program called eVGA Precision. You can use it to monitor temps and OC the vid cards. Do not know how well it works but will try it soon.
You will need a 64bit OS to use all of the 4gb of memory. If you have a 32bit OS it will only see around 3.2-3.4gb. If you have 32bit Vista and upgrade to SP1, which done through Windows Updates, it will see that 4GB is installed and will tell you but will not be able to use all of the 4GB due to the limit of a 32bit OS.
