New system

[paulp4als]

I would like to build a new system. I am looking at a quad Q6600 with a compatible graphics card possibly a Geforce 8800 GT. I need a motherboard & memory suggestion possibly 2Gb . I will be using this for games like COD4 as my current machine is at its limit for this game. I will be running Windows XP Pro
Please help

What is your budget here? Do you just need the system box itself or do you need peripherals, monitor etc? Will you be re-using any parts from your existing system?
