Hello guys I'm new to this forum thing and LAN parties. I'm trying to get a LAN party together for my friends bachelor party and I want to build XP machines that will play old school games. back in the day I had a Pentium D and a 9800gtx 512mb and it played decent games. I want to know if that will be enough to play games like left 4 dead 1-2, swat 4, doom 3, or is it overkill ( I am also open to AMD solutions). I will have to build 4 towers so I don't want to spend crazy money on them. just the basics for now. Thanks!
