Hello, I'm looking to upgrade parts in my computer but I don't have a great amount of knowledge as to what I should get and what I should look for. I have a 1680 by 1050 monitor, a 750 watt PSU, and 2 hard-drives, and a sound-card. I'm looking for a new Mobo, CPU, RAM, and a new graphics card. Unfortunately I only have about 400-500$ to spend on this. Can anyone help me put together components that work together properly and will be good to play games such as Guild Wars 2 on at least high settings @ 30+ fps? I have Win7 prof. so no need for a OS.
