My parents assigned me the task of building my own christmas/hannukah present. I've been all over Newegg trying to find the parts to do this well, and I came up with the following list: ThermalTake XASER case OCX Powerstream 520w PSU Asus A8N5X/ geForce 4 mobo Athlon 64 3700+ SD CPU Corsair Valueselect 1G RAM eVGA geForce 7800GT Western Digital Caviar 250G HDD, 16MB cache Sound Blaster x-fi sound card All of that comes to a 1179$ total. I was told that my total cost could be up to 1300. Is there anything that I'm missing, or any parts that could be replaced with better performing parts for around the same cost? The comp will be primarily used for gaming, and I already have an OS to install. I can provide links if necessary.
