Dual monitor

I don't know either this is the right place to ask or not. I just having my 2nd monitor. I just want to ask it is possible for me to play game and browsing the internet at the same time? The 2 monitors hooked up to the same graphic card. both of them is 23". So it is possible to play a full screen game on one monitor while also browsing the internet on the other monitor? I've tried it but whenever I click anything in the second monitor the game minimizes. My settings are set to extended display and I'm guessing that's the reason this happens but are there any settings I can change to make this possible. Basically having the 2 monitors be independent of each other. and this is my computer main spec:-

Motherboard: MSI Z77A-GD65
Graphic card: MSI Twin Frozr 2GD5 R7870
OS: Windows 8 64bit.

Thank you.

You should be able to achieve that by using your graphics card control panel. You will need to set up a display group first by combining the monitors and then selecting a monitor to be the primary monitor.

arent it will only combine my monitor? it will make both my monitor into either in the game or in the browser. :|
