Hello folks, below is the specs of my current build for my desktop. I currently get like 20fps in Dalaran and my buddy said WOW is CPU intensive so I'm looking to upgrade my CPU and motherboard. I started playing WOW again about 30 days ago and I can't stand the 20fps in Dalaran so looking to upgrade. I would like to add that I do use this computer to play other game such as league of legends and most new (AAA,) games that come out. I'm ok with computers but my big fear in doing this myself if I really don't know what would be compatible with what I have and am looking for. My budget for a CPU and motherboard is about $600 USD. Also, the reason why I'm updating the motherboard is because it's old and I plan on giving it to my brother.
