I am building my very first gaming pc. I will use an Intel core i3 3240 processor clocked at 3.4 GHz and 4 GB of Ram. My os will be windows 7 professional 64 bit. My motherboard is an Asus H61M-E All-in-one LGA1155. the graphics card will be the ASUS EAH6450 SILENT 1GD3. I will be gaming on this computer for games like battlefield 3 on medium settings. I want to know if this is a good first build?
