My parents, for some reason, ill not allow me to build a pc from scratch. I've looked on some websites but they are all way too overpriced for what they are. They have good processors but no graphical power. My budget is about $400-$450. The only requirement I have is that it be able to run Planetside 2 at 30fps on low. I may be able to replace the ram since it's easy to replace. Can anyone help?
