Hi, I am not sure if i need to upgrade my motherboard. I want to play battlefield 2 and it says that i need a 128Mb video card at least. I have a Nvidia Geforce4 MX 64mb. What I want to do is get a ATI Radeon 9800 Pro 128mb. I have an Emachines T2825 computer, and I have no idea what motherboard I have. How do I find out what motherboard I have? I also want to get pentium 4 3.0 processor. Will my motherboard run a pentium 4 processor, and an ATI Radeon 9800 Pro 128mb? Im stumped. Please give me some help.
