Hi Rahul_V, You can definately go ahead and purchase the Windows 7 Ultimate version based on your requirements. Microsoft plans to release Windows 8 for general availability on October 26, 2012. You could wait untill Windows 8 is released and check the requirements and the driver availability for your model  and then upgrade the Windows version.
