Which Mac Mini do I buy?

I am very tempted to buy a Mac Mini as my main everyday desktop, But I am confused between the base model(i3) and i5 model.My main use will be:

-Web Browsing
-Running Virtual Machines (Windows and Linux guests)
-Programming (Ios and android app programming)
-Gaming (Fifa 12 and Gta San Andreas)

Will the Base model of the mac mini suffice for me?I have heard that Intel Graphics ate slow as compared to the AMD Radeon HD 6630M.So which one will You all suggest?

You could go for the i5 model and still get $100 off
