OK I'm thinking about upgrading so I'm gonna need some advice on what to get. Currently I have an Asus P4E motherboard that's running a 1.4ghz cpu and have 512 RDRAM. I have a nice 128 mb AGP video card. I want to updagrad so I can play the new games like BF2 and the likes. What mobo/cpu combo should I look into. Thanks. I want to minimize cost.
