I want to build a computer that can run battle field 2 smoothly with no problems. I don't know a whole lot about performance stuff on computer but i do know how to build a computer. I'm starting with buying a motherboard and processor I'm hoping to spend 500 dollars but will spend 700 if i have to on just the 2 parts. Im not sure if this is realistic? I hurd there was some mother boards that used a special pci slot to run some pci graphics card faster then agp runs its cards. Is it worth getting a mother board with that? ANY SUGGESTIONS WHAT I SHOULD BUY? OR TIPS ON WHAT TO LOOK FOR? I would enjoy making the computer myself but do you save any money buy buying a whole computer?
