What is the cost for 4GB ram for 27" Mac? I already have 4GB and does it make much difference in the speed to increase to 8GB?

According to apple's customize page for iMacs, an extra 4GB of ram wil cost $100
RAM doesn't really increase your systems speed unless the RAM is actually faster or the current amount of system ram isn't enough for the OS (for the iMac upgrade it isn't faster and 4GB is sufficient enough for the operating system). What RAM does is act as a storage space for active programs and applications. For instance, if you have a web browser open with multiple tabs, all those tabs will be stored in RAM along with the web browser program itself. Data in RAM is suppose to be disposable so when you close the programs, the RAM that they occupied will be returned to a "Free" state where they can be used again by another program. More RAM is beneficial for programs like games, high resolution photo and video editing or if you plan on running a lot of programs or tasks at once.
The only way more ram will increase the speed of the system will be because it is running faster and more efficient (DDR3 1600 mhz versus DDR3 1333 mhz) or because what you are doing on the computer is using more RAM than what is available. OSX 10.7 and 10.8 use roughly 2GB of RAM for the operating system, leaving 2GB of RAM for the user if the system has 4GB total. In most cases that will be enough. The only way you will need more is if you find yourself running 15-20 browser tabs regularly on top of several other programs.
