that was no help. Your PC was running fine before with 2gb ram, right? you upgrade your vid card and get worse performance.......so how could this be caused by ram? it cant. What you should do when upgrading video cards is use Driversweeper. It removes all traces of old drivers and is free to download. Use this in safe mode to remove any nvidia and AMD display drivers. Then download and install the latest AMD display drivers. That would be a good start to help solve your problem. More ram is not the answer, but it is a good idea to have more than 2gb ram anyway.
