Q: SQL Server 2008 R2 or SQL Server 2012?

Question

Hello guys, my name is Dee, I'm a Systems Analyst and I would like to ask for your help regarding choosing the right SQL server? My project is to create a web application using ASP.NET but I need to submit a server proposal. Which would you recommend, SQL Server 2008 R2 or SQL Server 2012? And also, I am not a hardware person so I don't know what to put in my server proposal. Please help me.. Thank you, I would really appreciate it.
