Do you mean the Nvidia HD audio driver?

If you like FPS multiplayer i can recommend Titanfall. If you like co-op Shooter, give Borderlands 2 a chance. For a long singleplayer experience chose Skyrim.

I got GTA V on Xbox 360 and it's amazing. Surely i'll buy it for PC too just to play GTA Online with more friends.

Thanks to you @svl7s for your effort, i'll try this the next days and give you feedback.

Hello, i'm a 30 year old tech enthusiast living in Germany. I'm a owner of a Macbook Pro 2012, iMac 2010, iPad 4, iPhone 5, Xbox 360. My first steps to the world of computers was in the early 90's with a 80386. I modfied and build computers from then till now. Around 2010 I make the decision to use Apple products because the benefits of the OS X. I'm a Web Developer and in my thoughts there are better IDEs and better Unix/Linux support with the built-in terminal. My currently centerpiece is my 2010 iMac which I recently upgraded from Intel Core i5 680 to Intel Core i7 880, 1 TB HHD to 3 TB HDD and a 256 GB SSD (making a Fusion Drive) and the graphics card upgrade to a Nvidia Geforce GTX 780M.

Thanks man! That worked great on my Macbook in Boot Camp with Windows 8.

I needed to recovery lost data and can recommend Data Rescue from Prosoft. I was able to recovery almost all deleted files.

I upgraded my iMac 27" twice. First from the stock Radeon HD 5750 Mobility to the Radeon HD 6970m from the newer 2011 Model and a month ago to a Geforce GTX 780M. As expected i lost my initial boot screen with the upgrade to the Geforce GTX 780M because the card doesn't have UEFI Bios. So, any card until the Geforce GTX 700 Series should work on an iMac which support MXM cards (2011 is the last model, graphics card in the 2012 and newer iMacs are soldered to the logic bord).
