I need to build a new computer so I can play Half Life 2 properly and give my current one to my parents. I'm extremely knowledgeable of software but I've neglected keeping up with the hardware side over the years. I've got $800 to spend on a tower, motherboard, processor, RAM and graphics card. I'm not willing to spend more than $300 on a video card. I already have a new Maxtor 250mb HD and a soundcard. I just need ya'll to help me with the rest of the parts ;f Is it worth the extra dough for an AMD 64 bit setup? Should I go with AMD or Intel mobo and processor? This is going to be a Windows XP machine. Thanks in advance!
